Module segment 

chronix-segment

Columnar segment file format (.csx) for the Chronix time-series database.

Segment files are immutable, columnar data files that store time-series data after it has been flushed from the memtable. Each segment contains:

• A header with file metadata (version, row count, time range).
• One or more row groups, each containing encoded column blocks.
• Column metadata enabling selective column reads.
• A footer with CRC32c integrity checksum.
