Add Kafka Storage Support for Arrow Formats
Add support for Kafka storage withArrowandArrowStreamformat messages. #23415 (Chao Ma).
Why it matters
This feature enables ClickHouse users to ingest data from Kafka topics where messages are serialized in Apache Arrow formats. It solves the problem of integrating high-performance columnar data interchange formats directly into Kafka storage, improving data processing efficiency and compatibility.How to use it
To use this feature, configure the Kafka engine table with theformat setting set to either Arrow or ArrowStream. For example, create a Kafka table with FORMAT = 'Arrow' or FORMAT = 'ArrowStream' to consume messages in these formats.
