Parallel parsing is now enabled by default for TSV, TSKV, CSV, and JSONEachRow data formats in ClickHouse.

Why it matters

This feature improves data ingestion performance by enabling parallel parsing of common text-based data formats, reducing query latency and increasing throughput when importing large datasets.

How to use it

No explicit action is required as parallel parsing is enabled by default for the supported formats. Users can simply continue loading data in TSV, TSKV, CSV, or JSONEachRow formats and benefit from improved parsing performance automatically.
