gabotechs opened a new pull request, #12084: URL: https://github.com/apache/arrow-rs/pull/12084
## Summary Stacked on #12083 — only the last commit (`compression.rs`) is new here; the diff will shrink to just that once #12083 merges. - Caches the `lz4_flex` `FrameEncoder` (hash table + block buffers) in `IpcWriteContext` and reuses it across `compress_lz4` calls instead of allocating a fresh encoder per buffer, mirroring the existing zstd context reuse. - Pins the frame's block size to 256KB so a reused encoder's block size isn't fixed by the first buffer it ever wrote. - On error mid-frame, drops the cached encoder so the next call starts fresh. ## Test plan - [x] `cargo test -p arrow-ipc --features lz4` passes, including new `test_lz4_compression_reuses_context` - [x] Benchmarks added in #12083 show the expected improvement from buffer reuse 🤖 Generated with [Claude Code](https://claude.com/claude-code) -- This is an automated message from the Apache Git Service.
