Implement ArrowWriter pooling #444
Description
Search before asking
- I searched in the issues and found nothing similar.
Description
Java pools ArrowWriter instances per table/schema via ArrowWriterPool. Reused writers keep their allocated vectors and seed the fullness threshold from the previous batch (recordsCount / 2), avoiding reallocation and the first-record size check on every new batch. We currently create a fresh MemoryLogRecordsArrowBuilder per batch.
