Users can now use NATS JetStream

Why it matters

This feature enables users to integrate ClickHouse with NATS JetStream, allowing efficient streaming data ingestion directly from NATS message streams. It solves the need for real-time, reliable message consumption within ClickHouse using native support for NATS JetStream.

How to use it

To use this feature, define a table with the NATS engine and specify the nats_stream and nats_consumer settings, for example:

CREATE TABLE example_table (
    ...columns...
) ENGINE = NATS(
    'nats://localhost:4222',
    'nats_stream', 'your_stream_name',
    'nats_consumer', 'your_consumer_name'
);
