Frequently Asked Questions

What is stream processing?

Continuously processing events as they arrive, with state, windows and low latency, instead of waiting for batch jobs.

How do I choose?

Consider latency, state management, exactly-once guarantees, SQL support, ecosystem fit and whether you want a managed service. Flink is the common choice for stateful low-latency work, Spark suits teams already on Spark, and streaming databases such as RisingWave and Materialize suit teams that prefer SQL.

Which vendors and projects are listed?

Open-source engines Flink, Spark, Storm, Samza and Beam, streaming databases such as RisingWave and Materialize, managed cloud services, and commercial products from SAS, Oracle, TIBCO, IBM, SAP, Informatica, Striim and others.

What related pages are there?

Real-time Data Analytics, Real-time Embedded DBMS, Data Analytics and the Real-Time Computing hub.
