Açıklaması şöyle

ksqlDB is an Event Streaming Database. Basically, you turn Kafka Streams (topics) into Databases. Allowing you to have some level of consistency and fast lookups on real-time data. ksqlDB allows you to perform SQL queries on your Kafka topics. It’s possible todo pull-based or even push-based queries.

Altta RocksDB kullanır. Açıklaması şöyle

Behind the scenes, ksqlDB uses RocksDB to store the contents of the materialized view. RocksDB is an embedded key/value store that runs in process in each ksqlDB server — you do not need to start, manage, or interact with it.

The beauty is that RocksDB abstracts away the complexity of storing and indexing an associative data structure on a disk with high performance. As a developer, that lets you focus on the stream processing logic rather than battling state management.
