Vortex FSST

A Vortex Encoding for Binary and Utf8 data that utilizes the Fast Static Symbol Table compression algorithm.

LIKE Pushdown

The FSST encoding has a specialized LIKE fast path for a narrow subset of patterns:

• prefix%
• %needle%

Unsupported shapes, including _, %suffix, or patterns with interior wildcards, fall back to ordinary decompression-based LIKE evaluation.

There are also two implementation limits on the pushdown path, both measured in pattern bytes:

• prefix% supports up to 253 bytes.
• %needle% supports up to 254 bytes.

Patterns beyond those limits are still evaluated correctly, but they do so via the fallback path instead of the DFA matcher.
