Rockset is a real-time analytics database service for serving low latency, high concurrency analytical queries at scale. It builds a Converged Index™ on structured and semi-structured data from OLTP databases, streams and lakes in real-time and exposes a RESTful SQL interface.

Built-in Connectors

Securely ingest data using native connectors with MongoDB, DynamoDB, Kafka, Kinesis, S3 and GCS. Rockset initially bulk loads data and then switches to continuous ingest to stay in sync with your source. Ingest millions of events per second. New data is queryable with p95 of 2 seconds. No ETL tools required.

Continuous Rollups and Transformations

Pre-aggregate and transform data at ingest time using SQL. Reduce the cost of storing and querying high-volume streaming data by up to 100x, and eliminate the need for separate real-time data pipelines.

SQL Views

Views are stored SQL queries that can be queried like all other persistent data in Rockset. Not only are views good for defining a collection without using extra storage, but they also accelerate data analysis and can provide your data extra security by limiting the exposure of the underlying data to others.

Smart Schemas

Smart schemas are automatically generated schemas based on the exact fields and types present in the ingested data. The schema represents semi-structured data, nested objects and arrays, mixed types and nulls, enabling relational SQL queries over all these constructs. No more schema drift.

{"user_id": "caligralist", ...},
{"user_id": none, ...},
{"user_id": "hacker123", ...},
{"user_id": 413452322, ...},
$ DESCRIBE typing_system_demo
['user_id']   4232 / 8312   string
['user_id']   3267 / 8312   int
['user_id']    813 / 8312   null_type
['...']               ...   ...
Converged Index™

All fields, including deeply nested fields, are automatically indexed in a Converged Index™ which includes an inverted index, columnar index and row index. A Converged Index™ compiles indexes of information and allows analytical queries on large datasets to return in milliseconds.

Full SQL

Run standard SQL queries, including filters, sorts, aggregations, inner and outer joins, directly on semi-structured data. Greater flexibility to query constantly changing, semi-structured and heavily nested data.

Query ran in ms.
Query Lambdas

Query Lambdas are named parameterized SQL queries stored in Rockset that can be executed from a dedicated REST endpoint. With Query Lambdas, you can enforce version control and integrate into your CI/CD workflows. Or use our Node.js, Java, Go, Python client libraries.

$ rock sql "SELECT 
        visits.promotion AS promotion, 
        sum(visits.converted)/count(visits.converted) AS clickthrough 
    FROM visits 
    GROUP BY clickthrough"
Separation of Compute and Storage

Scale compute and storage resources independently for the best price-performance. As your data size grows, you can use exactly the right amount of compute for the query performance you need at any given time.

Serverless Auto-Scaling in the Cloud

Rockset uses a modern, cloud-native Aggregator Leaf Tailer (ALT) architecture which auto-scales in the cloud and automates cluster provisioning and index management. Optimize costs while minimizing operational overhead with serverless auto-scaling.

Enterprise-Grade Security

Rockset is SOC2 Type II compliant and offers several security features including role based access with custom roles, enhanced authentication management with MFA and Okta SSO, and the ability to mask sensitive information using field mappings at the time of ingest. All data is encrypted at rest and SSL in transit. Optional support for AWS VPC deployments.

Sample APIs

Explore sample APIs for read-intensive applications like recommendation engines, personalization features, geo-tracking services and more. Using Query Lambdas you can save your SQL query as a dedicated endpoint and turn it into an API.

Optimized for Speed

  • A Fully Mutable Converged Index™

    A Converged Index™ stores each individual field of the document as an independently addressable key in an inverted, columnar and row index. It is fully mutable at the field level which means Rockset can keep up with high rate of inserts, updates and deletes by updating a single key without having to re-index the entire document.

  • Massive Write Rate

    Use of RocksDB's LSM trees, an in-memory buffer to cache incoming writes and a lockless protocol makes writes visible to existing queries as soon as they happen. Remote compaction speeds up indexing even in the face of bursty writes.

  • Microsharding

    Your index is document sharded for low latency. It is organized in the form of thousands of micro-shards, to eliminate the need for re-indexing. This is a key enabler for indexing massive cloud-scale data sets. Rockset automatically rebalances and distributes shards across a cluster.

  • Distributed Query Execution

    A cost-based optimizer selects the optimal indexes and a distributed query engine executes each portion of the query with shard-level parallelism. A query hits all shards in the index, processes the query in parallel and returns results faster, unlike Cassandra, HBase, Aurora and Citus which are term-sharded.

  • RocksDB on SSD

    Rockset stores all indexes on RocksDB using SSD for hot storage, backed by S3 for durable storage. Built and open-sourced by the Rockset founding team, RocksDB is a high performance embedded storage engine used by other modern datastores like CockroachDB, Kafka, Flink.
