Architecture

Single-node (in-memory)

complete
SurrealDB can be configured to run in a single-node memory-only runtime, enabling multi-reader, single-writer querying and data analysis. This is suitable for testing and for data which fits inside the memory capacity of a single machine.

Web browser (IndexedDB)

complete
When wanting to use SurrealDB from within the browser, the WebAssembly library has support for connecting to a remote database over HTTP or WebSockets, or running with data persistence on top of IndexedDB in the browser.

Single-node (SurrealKV)

beta
Our own native storage engine, written in Rust supports multiple concurrent writers and readers. SurrealKV introduces versioned queries over time, enabling immutable data querying, data change auditing, historic aggregate query analysis, and versioned queries on the graph.

Distributed (SurrealKV)

in development
For highly-available setups, SurrealKV will support the ability to horizontally scale to multiple terabytes of data. As a distributed cluster SurrealKV will enable versioned queries over time, enabling immutable data querying, data change auditing, historic aggregate query analysis, and versioned queries on the graph.
Single-node (<a href='https://rocksdb.org/'>RocksDB</a>)

Single-node (RocksDB)

complete
When wanting persistent data storage on a single-node, on-disk storage can be used to enable larger data storage capabilities. RocksDB is optimised for high performance and fast storage on SSDs.
Distributed (<a href='https://tikv.org/'>TiKV</a>)

Distributed (TiKV)

complete
For highly-available and highly-scalable setups, SurrealDB can be run on top of a TiKV cluster, with the ability to horizontally scale to multiple terabytes of data.

Platform

Multi-tenancy data separation

complete
Split data into namespaces and databases. There is no limit to the number of databases under each namespace, with the ability to switch between databases inside queries and transactions.

Schemafull or schemaless

complete
Store unstructured nested data with any columns, or limit data stored to only specific columns or fields. Get started quickly without having to define every column, and move to schemafull when your data model is defined.

Multi-table, multi-row transactions

complete
As a fully ACID compliant database, SurrealDB allows you to run transactions across multiple-rows, and across multiple different tables. There is no limit to the length of time a transaction can run.

Versioned temporal tables

in development
Versioned temporal tables enable the option to 'go back in time' when querying your data. See how data looked before changes were made, or restore to a particular point-in-time.

Table fields

complete
When a table is defined as schemafull, only data allowed by defined fields will be stored. Table fields can be nested, and can be limited to a certain data type. VALUE clauses can be used to ensure a default value is always specified if no data is entered.

Table events

complete
Table events can be triggered after any change or modification to the data in a record. Each trigger is able to see the $before and $after value of the record, enabling advanced custom logic with each trigger.

Table indexes

complete
Table indexes improve data querying performance, and also allow for UNIQUE values in a table. Table indexes can be specified for a column, multiple columns, and have support for all nested fields including arrays and objects.
-- Specify a field on the user table DEFINE FIELD email ON TABLE user TYPE string ASSERT string::is::email($value); -- Add a unique index on the email field to prevent duplicate values DEFINE INDEX email ON TABLE user COLUMNS email UNIQUE; -- Create a new event whenever a user changes their email address DEFINE EVENT email ON TABLE user WHEN $before.email != $after.email THEN ( CREATE event SET user = $this, time = time::now(), value = $after.email, action = 'email_changed' );

Table constraints

complete
Each defined table field supports an ASSERT clause which acts as a constraint on the data. This clause enables advanced SurrealQL statements which can ensure that the $value entered is within certain parameters. Each clause is also able to see the $before and $after value of the record, enabling advanced custom logic with each trigger.
-- Specify a field on the user table DEFINE FIELD countrycode ON user TYPE string -- Ensure country code is ISO-3166 ASSERT $value = /[A-Z]{3}/ -- Set a default value if empty VALUE $value OR $before OR 'GBR' ;

Full text indexing and filtering

complete
The ability to define full-text indexes, with functionality to search through the full-text index on a table. Searches support field queries, configurable text analyzers, relevance matching, highlighting with offsets extraction.
-- Define a text analyzer DEFINE ANALYZER en TOKENIZERS camel,class FILTERS snowball(English); -- Define a search index for a field on the book table DEFINE INDEX search_title ON book COLUMNS title SEARCH ANALYZER en BM25 HIGHLIGHTS; -- Select all books who match given keywords SELECT search::score(1) AS score, search::highlight('<b>', '</b>', 1) AS title FROM book WHERE title @1@ 'rust web' ORDER BY score DESC;

Vector embedding indexing

complete
Indexing of vector embeddings, with support for euclidean distance metrics. Vector embeddings can be used for similarity matching, and for advanced data analysis.
-- Add vector embedding data to record content CREATE article:1 SET embedding = [1, 2, 3, 4]; CREATE article:2 SET embedding = [4, 5, 6, 7]; CREATE article:3 SET embedding = [8, 9, 10, 11]; -- Define a vector embedding index for a field on the article table DEFINE INDEX mt_obj ON vec FIELDS embedding MTREE DIMENSION 4 DIST EUCLIDEAN;

Aggregate analytics views

complete
Aggregate views let you pre-compute analytics queries as data is written to SurrealDB. Similarly to an index, a table view lets you select, aggregate, group, and order data, with support for moving averages, time-based windowing, and attribute-based counting. Pre-defined aggregate views are efficient and performant, with only a single record modification being made for every write.
-- Drop all writes to the reading table. We don't need every reading. DEFINE TABLE reading DROP; -- Define a table as a view which aggregates data from the reading table DEFINE TABLE temperatures_by_month AS SELECT count() AS total, time::month(recorded_at) AS month, math::mean(temperature) AS average_temp FROM reading GROUP BY city ; -- Add a new temperature reading with some basic attributes CREATE reading SET temperature = 27.4, recorded_at = time::now(), city = 'London', location = (-0.118092, 51.509865) ;

Live queries and record changes

complete
Live SQL queries allow for advanced filtering of the changes to specific documents, documents which match a particular filter, or all documents in a specific table. Live SQL queries can send the fully-updated document, or only the document changesets, by using the efficient DIFF-MATCH-PATCH algorithm for highly-performant web-based data syncing.
-- Subscribe to all matching document changes LIVE SELECT * FROM document WHERE account = $auth.account OR public = true ; -- Subscribe to all changes to a single record LIVE SELECT * FROM post:c569rth77ad48tc6s3ig; -- Stop receiving change notifications KILL "1986cc4e-340a-467d-9290-de81583267a2";

Global parameters

complete
Global parameters can be used to store values across the database, which are then accessible to all queries.
-- Define a global parameter which will be accessible to all queries. DEFINE PARAM $STRIPE VALUE "https://api.stripe.com/payments/new"; -- Use the defined global parameter in all queries on the database. DEFINE EVENT payment ON TABLE order WHEN $event = 'CREATE' THEN http::post($STRIPE, $value);

Data model

Basic types

complete
Support for booleans, strings, and numerics is built in by default. Numeric values default to decimal based numbers, but can be stored as int or float values for 64 bit integer or 64 bit floating point precision.

Empty values

complete
Values can be NONE, or NULL. A field which is NONE does not have any data stored, while NULL values are values which are entered but empty.

Arrays

complete
SurrealDB has native support for arrays, with no limit to the depth of nesting within arrays. Arrays can contain any other data value.

Objects

complete
Embedded object types are an integral feature of SurrealDB, with no limit to the depth of nesting for objects.

Durations

complete
Any duration from nanoseconds to weeks can be stored and used for calculations. Durations can be added to datetimes, and to other durations.

Datetimes

complete
Support for dates and datetimes in ISO-8601 format are supported. All dates are converted and stored in the UTC timezone.

Geometries

complete
SurrealDB makes working with GeoJSON easy, with support for Point, Line, Polygon, MultiPoint, MultiLine, MultiPolygon, and Collection values. SurrealQL automatically detects GeoJSON objects converting them into a single data type.
UPDATE city:london SET centre = (-0.118092, 51.509865), boundary = { type: "Polygon", coordinates: [[ [-0.38314819, 51.37692386], [0.1785278, 51.37692386], [0.1785278, 51.61460570], [-0.38314819, 51.61460570], [-0.38314819, 51.37692386] ]] } ;

Futures

complete
Values which should be computed only when outputting data, can be stored as futures. These values are stored in SurrealDB as SurrealQL code, and are calculated only when output as part of a SELECT clause.
UPDATE product SET name = "SurrealDB", launch_at = <datetime> "2021-11-01", countdown = <future> { launch_at - time::now() } ;

Casting

complete
In SurrealDB, all data values are strongly typed. Values can be cast and converted to other types using specific casting operators. These include bool, int, float, string, number, decimal, datetime, and duration casts.
UPDATE person SET waist = <int> "34", height = <float> 201, score = <decimal> 0.3 + 0.3 + 0.3 + 0.1 ;

Strict typing

complete
With a strict typing system, SurrealQL ensures that document structures are easier to understand, and any data conforms to the defined record schema. Advanced types for arrays and record links, ensure that related data works in the same way as basic types.
// Ensure that a record field must be a number. DEFINE FIELD age ON person TYPE number; // Allow the field to be optional or a number. DEFINE FIELD age ON person TYPE option<number>; // Ensure that a record link is specified and of a specific type. DEFINE FIELD author ON book TYPE record<person>; // Allow a field to be optional and of a selection of types. DEFINE FIELD pet ON user TYPE option<record<cat | dog>>; // Allow a field to be one of multiple types. DEFINE FIELD rating ON film TYPE float | decimal; // Ensure that a field is an a array of unique values of a certain length. DEFINE FIELD tags ON person TYPE set<string, 5>;

SurrealQL

SELECT, CREATE, UPDATE, DELETE statements

complete
Manipulation and querying of data in SurrealQL is done using the SELECT, CREATE, UPDATE, and DELETE methods. These enable selecting or modifying individual records, or whole tables. Each statement supports multiple different tables or record types at once.
-- Create a new article record with a specific id CREATE article:surreal SET name = "SurrealDB: The next generation database"; -- Update the article record, and add a new field UPDATE article:surreal SET time.created = time::now(); -- Select all matching articles SELECT * FROM article, post WHERE name CONTAINS 'SurrealDB'; -- Delete the article DELETE article:surreal;

RELATE statements

complete
The RELATE statement adds graph edges between records in SurrealDB. It follows the convention of vertex -> edge -> vertex or noun -> verb -> noun, enabling the addition of metadata to the edge record.
-- Add a graph edge between user:tobie and article:surreal RELATE user:tobie->write->article:surreal SET time.written = time::now() ; -- Add a graph edge between specific users and developers LET $from = (SELECT users FROM company:surrealdb); LET $devs = (SELECT * FROM user WHERE tags CONTAINS 'developer'); RELATE $from->like->$devs UNIQUE SET time.connected = time::now() ;

INSERT statements

complete
The INSERT statement resembles the traditional SQL statement, enabling users to get started quickly. It supports the creation of records using a VALUES clause, or by specifying the record data as an object.
INSERT INTO company { name: 'SurrealDB', founded: "2021-09-10", founders: [person:tobie, person:jaime], tags: ['big data', 'database'] }; INSERT IGNORE INTO company (name, founded) VALUES ('SurrealDB', '2021-09-10') ON DUPLICATE KEY UPDATE tags += 'developer tools' ;

FOR statements

complete
FOR statements enable simplified iteration over data, or for advanced logic when dealing with nested arrays or recursive functions, within code blocks or custom functions.
FOR $person IN (SELECT VALUE id FROM person) { CREATE gift CONTENT { recipient: $person, type: "ticket", date: time::now(), event: "SurrealDB World", }; };

THROW statements

complete
The THROW statement statement can be used to return custom error types, which allow for building advanced programming and business logic right within the database and authentication engine.
FOR $user IN $input { IF $user.age < 18 { THROW "Only adults should be inserted"; } IF $user.country != 'USA' { THROW $user.country + " is not a valid country"; } };

Parameters

complete
Parameters can be used to store values or result sets, and can be used as stored parameters in client code.

Subqueries

complete
Recursive subqueries are useful for advanced querying or modification of values, whilst simplifying the overall query.

Nested field queries

complete
In SurrealQL any nested array or object value can be accessed and manipulated using traditional dot notation ., or array notation [].

Maths operators

complete
Maths operators can be used to perform complex mathematical calculations directly in SurrealQL.

Geo operators

complete
Geospatial operators enable geospatial containment and intersection operators on geospatial types.

Set operators

complete
Advanced set operators can be used to detect whether one or multiple values are included within an array. Fuzzy matching and regex matching can also be used for advanced filtering.
-- Use mathematical operators to calculate value SELECT * FROM temperature WHERE (celsius * 1.8) + 32 > 86.0; -- Use geospatial operator to detect polygon containment SELECT * FROM restaurant WHERE location INSIDE { type: "Polygon", coordinates: [[ [-0.38314819, 51.37692386], [0.1785278, 51.37692386], [0.1785278, 51.61460570], [-0.38314819, 51.61460570], [-0.38314819, 51.37692386] ]] }; -- Select all people whose tags contain "tag1" OR "tag2" SELECT * FROM person WHERE tags CONTAINSANY ["tag1", "tag2"]; -- Select all people who have any email address ending in 'gmail.com' SELECT * FROM person WHERE emails.*.value ?= /gmail.com$/;

Maths constants

complete
SurrealQL has a number of built-in constants for advanced mathematical expressions and calculations, including math::E, math::FRAC_1_PI, math::FRAC_1_SQRT_2, math::FRAC_2_PI, math::FRAC_2_SQRT_PI, math::FRAC_PI_2, math::FRAC_PI_3, math::FRAC_PI_4, math::FRAC_PI_6, math::FRAC_PI_8, math::LN_10, math::LN_2, math::LOG10_2, math::LOG10_E, math::LOG2_10, math::LOG2_E, math::PI, math::SQRT_2, and math::TAU.

Expressions

complete
SurrealQL supports fetching data using dot notation ., array notation [], and graph semantics ->. SurrealQL enables records to link to other records and traverses all embedded links or graph connections as desired. When traversing and fetching remote records SurrealQL enables advanced filtering using traditional WHERE clauses.
-- Select a nested array, and filter based on an attribute SELECT emails[WHERE active = true] FROM person; -- Select all 1st, 2nd, and 3rd level people who this specific person record knows, or likes, as separate outputs SELECT ->knows->(? AS f1)->knows->(? AS f2)->(knows, likes WHERE influencer = true AS e3)->(? AS f3) FROM person:tobie; -- Select all person records (and their recipients), who have sent more than 5 emails SELECT *, ->sent->email->to->person FROM person WHERE count(->sent->email) > 5; -- Select other products purchased by people who purchased this laptop SELECT <-purchased<-person->purchased->product FROM product:laptop; -- Select products purchased by people in the last 3 weeks who have purchased the same products that we purchased SELECT ->purchased->product<-purchased<-person->(purchased WHERE created_at > time::now() - 3w)->product FROM person:tobie;

Complex Record IDs

complete
SurrealDB supports the ability to define record IDs using arrays and objects. These values sort correctly, and can be used to store values or recordings in a timeseries context.
// Set a new parameter LET $now = time::now(); // Create a record with a complex ID using an array CREATE temperature:['London', $now] SET location = 'London', date = $now, temperature = 23.7 ; // Create a record with a complex ID using an object CREATE temperature:{ location: 'London', date: $now } SET location = 'London', date = $now, temperature = 23.7 ;

Record ID ranges

complete
SurrealDB supports the ability to query a range of records, using the record ID. The record ID ranges, retrieve records using the natural sorting order of the record IDs. These range queries can be used to query a range of records in a timeseries context.
-- Select all person records with IDs between the given range SELECT * FROM person:1..1000; -- Select all records for a particular location, inclusive SELECT * FROM temperature:['London', NONE]..=['London', time::now()]; -- Select all temperature records with IDs less than a maximum value SELECT * FROM temperature:..['London', '2022-08-29T08:09:31']; -- Select all temperature records with IDs greater than a minimum value SELECT * FROM temperature:['London', '2022-08-29T08:03:39']..; -- Select all temperature records with IDs between the specified range SELECT * FROM temperature:['London', '2022-08-29T08:03:39']..['London', '2022-08-29T08:09:31'];

SurrealML

Custom machine learning models

complete
Use SurrealML to train custom machine learning models in Python, using PyTorch, Tensorflow, or Sklearn. The models are stored in a custom .surmldata-format, enabling the model to be run consistently and safely in Python, Rust, or SurrealDB. Models can then be imorted into SurrealDB, allowing for Inference directly against any data in the database.
from surrealml import SurMlFile # Specify the trained model, model name, and model inputs file = SurMlFile(model=model, name="house::price::prediction", inputs=test_inputs) # Add a description for this model that can be viewed in teh database file.add_description("This model predicts the price of a house based on its square footage and number of floors.") # Add a version identifier which enables specific model versions to be run separately file.add_version("0.3.0") # Optionally define named input fields and data normalisation functions file.add_column("squarefoot") file.add_column("num_floors") file.add_normaliser("squarefoot", "z_score", squarefoot_mean, squarefoot_std) file.add_normaliser("num_floors", "z_score", num_floors_mean, num_floors_std) # Optionally specify named output fields with normalisation functions file.add_output("house_price", "z_score", house_price_mean, house_price_std) # Save the .surml file, ready to execute or import into the database file.save("./my_model.surml")

Model inference in Python

complete
Inference on .surml model files in Python allows for consistent and reproducible modeel computation in development, continuous integration, testing, or production environments.
from surrealml import SurMlFile # Load the model file from disk model = SurMlFile.load("./my_model.surml") # Perform raw vector compute against the model output = model.raw_compute([1.0, 2.0], [1, 2]) # Perform named buffered compute against the model output = model.buffered_compute({ "squarefoot": 3200.0, "num_floors": 2.0 })

Model inference in SurrealDB

complete
Model inference within SurrealDB is powered by a Rust-native runtime, backed by ONNX, with support for PyTorch, Tensorflow, and Sklearn models. This secure, and performant runtime allows for CPU and GPU model inference right alongside the data within the database. Field are automatically mapped to the right position for the model input tensors, and normalisations, if specified, are automatically applied to any input values, reducing errors of implementation of the models when deployed.
-- Perform raw computation against the imported model RETURN ml::house::price::prediction<0.3.0>( [1.0, 2.0], [1, 2] ); -- Perform named buffered computation against the imported model SELECT *, ml::house::price::prediction<0.3.0>({ squarefoot: squarefoot_col, num_floors: num_floors_col }) AS price_prediction FROM property_listing WHERE price_prediction > 177206.21875 ;
