• Freshness-Responsiveness Balancers - Balances query freshness against response speed by selecting a timestamp that returns recent data without waiting.
• Point-In-Time Snapshots - Assigns a timestamp to each query and returns results as of that moment for consistent snapshots.
• Persistence & Durability - Stores materialized view state durably on disk for crash recovery and instant reads.
• Differential Dataflow Engines - Computes incremental view updates by propagating changes through a data-parallel, timely dataflow graph.
• Consistent Ingestion Timestampers - Ingests tables from external sources and assigns each transaction a common timestamp for consistency.
• CDC Sources - Continuously ingests MySQL changes via GTID-based binlog replication with transactional consistency.
• Continuous SQL Querying - Executes SQL queries that incrementally update results as underlying streaming data changes.
• Model Context Protocol Servers - Ships an MCP server that exposes live materialized view data to AI agents for real-time context.
• Stream Adapters - Consumes messages from Kafka or Redpanda topics, decoding Avro, Protobuf, JSON, and CSV formats.
• Materialized Views - Answers analytical queries against continuously updated materialized views using PostgreSQL-compatible clients.
• Consistent View Maintainers - Keeps materialized views incrementally updated with consistent snapshots across all data sources.
• Incremental View Refreshes - Updates materialized views by processing only changed rows rather than full dataset recalculation.
• PostgreSQL-Compatible Databases - Accepts standard SQL queries via the PostgreSQL wire protocol for real-time analytical workloads.
• PostgreSQL Protocol Compatibility - Accepts standard SQL queries over a PostgreSQL-compatible interface, enabling existing tools to work unchanged.
• Real-Time Recency Guarantees - Ensures SELECT results include all data visible to external sources at query time.
• Real-Time Data Streaming - Ingests live data streams and incrementally maintains materialized views for up-to-date query results.
• Change Data Capture Protocols - Continuously reads upstream database replication logs and maps them to differential dataflow updates.
• Lock-Step Source Ingesters - Brings in tables from external databases as a single consistent unit, updating all tables in lock-step.
• Streaming Data Sources - Reads live data from PostgreSQL, MySQL, Kafka, and webhooks for continuous streaming ingestion.
• PostgreSQL Dialect Transformations - Supports full PostgreSQL-dialect SQL for transforming streaming data with joins, aggregations, and recursion.
• Serializable Snapshot Isolation - Guarantees serializability without linearizability, allowing slightly stale but consistent snapshots for lower latency.
• Strict Serializability - Guarantees both serializability and linearizability so the serial order matches the real-time order of transactions.
• Strong Consistency Guarantees - Runs queries at a level that prevents dirty reads, non-repeatable reads, and phantoms without real-time ordering.
• Stream Ingestion - Reads live data directly from PostgreSQL/MySQL replication streams, Kafka, or webhooks to keep the database continuously updated.
• Kafka Stream Ingestion - Continuously ingests data from Kafka and Redpanda topics into streaming SQL sources.
• Isolation Level Configuration - Lets each session choose between strict serializable, serializable, or bounded-staleness consistency.
• Isolation Level Management - Controls which concurrent-transaction effects are visible during a query by setting the session's isolation level.
• Lock-Step Table Ingesters - Brings in tables from an external source that update in lock-step, ensuring consistency across tables.
• Staleness-Bound Query Enforcements - Serves queries at a timestamp within a configurable staleness bound, erroring if the bound cannot be met.
• Query Timestamp Selectors - Picks a timestamp on the shared timeline for each query to balance freshness, responsiveness, and consistency.
• Freshness-Consistency Balancers - Lets users choose a query timestamp that balances responsiveness, freshness, and consistency.
• Consistency Level Selectors - Selects the consistency guarantee for a session or transaction, balancing freshness against query latency.
• Distributed Dataflow Runtimes - Schedules and coordinates distributed dataflow operators using epoch-based progress tracking.
• Multi-Source Timestamp Coordinators - Assigns a shared logical timestamp to all incoming data from external sources for consistent snapshots.
• Data Change Subscriptions - Streams incremental result changes to clients via SUBSCRIBE, Kafka topics, or object storage for push-based delivery.
• Debezium Change Event Decoders - Decodes Debezium change events from Kafka to incrementally update materialized views.
• Live Change Exporters - Pushes view changes to Kafka topics, object storage, or clients via SUBSCRIBE for real-time downstream consumption.
• Avro Decoding - Decodes Avro messages from Kafka topics using Confluent Schema Registry schemas for typed SQL columns.
• Upsert by Key - Interprets Kafka messages as key-value pairs to insert, update, or delete rows based on key content.
• JSON Array Iteration - Splits a JSON array payload into individual rows, one per array element.
• JSON Body Decoders - Decodes the HTTP body as JSON or newline-delimited JSON and stores it as a jsonb column, rejecting invalid payloads.
• Persistence Layers - Stores view state durably on disk using a columnar format that survives restarts and supports incremental checkpointing.
• Incremental View Exporters - Pushes incremental view changes to a Kafka topic or object storage as they occur.
• Live Update Subscriptions - Streams incremental updates to views via SUBSCRIBE, Kafka topics, or object storage for push-based consumption.
• Recursive CTE Queries - Computes fixed-point results for mutually recursive common table expressions, iterating bindings until no changes remain.
• Non-Linear Recursions - Supports non-linear recursive CTEs for advanced SQL computation like graph algorithms and dynamic programming.
• PostgreSQL Data Sources - Creates sources that subscribe to PostgreSQL publications for continuous data ingestion.
• Redpanda Stream Ingestion - Ingests data from Redpanda topics using the Kafka-compatible streaming source interface.
• Cloud Deployment Services - Runs as a fully-managed cloud offering that handles infrastructure, scaling, and operations automatically.
• SQL Project Deployments - Compiles, tests, and deploys declarative SQL projects to a database environment.
• Webhook - Accepts HTTP POST requests at a public URL and stores the request body as rows in a streaming SQL source.
