Improved Binary Format Performance for Strings and Arrays

Improved performance of reading strings and arrays in binary formats. Amos Bird
Improved the performance of reading strings and arrays in ClickHouse's binary formats.

Why it matters

This enhancement optimizes the binary format parsers for strings and arrays, reducing the CPU overhead and accelerating data ingestion and processing when working with binary encoded input. It provides users with faster query performance and improved efficiency when handling binary data types.

How to use it

The improvement is applied internally in ClickHouse and requires no special user action. Users benefit automatically from this optimization when reading strings and arrays in binary formats, such as the Native or other binary input formats supported by ClickHouse.
