Streaming Platforms

01Hazelcast

A streaming platform with integrated distributed storage to serve processed live data straight to applications — combining stream processing with in-memory computing.

02Materialize

A SQL streaming database: stream your data, perform real-time joins, and build live, incrementally updated views using standard Postgres-compatible SQL.

03ksqlDB

Confluent's database purpose-built for stream processing on Apache Kafka — build real-time applications with the same ease as a traditional relational database.

04Qlik Data Streaming (CDC)

Log-based, agentless change data capture that delivers large volumes of real-time, analytics-ready data into streaming platforms, warehouses, and data lakes.

Streaming databases let you query data in motion with familiar SQL — continuously updating results as new events arrive, instead of running batch queries against data at rest.
