hubgeter opened a new pull request, #64449:
URL: https://github.com/apache/doris/pull/64449
pick #61245
Fix:
- Fix potential memory leak in MaxComputeJniScanner by closing
currentSplitReader in close().
- Fix potential memory leak in MaxComputeJniWriter by restructuring close()
with try-finally to ensure allocator is always closed even when
batchWriter.commit() throws. Also close VectorSchemaRoot after each batch write.
- Fix maxWriteBatchRows parameter key mismatch between BE
("max_write_batch_rows") and JNI ("mc.max_write_batch_rows"), which caused
user-customized values to be silently ignored.
Optimization:
- Split large Arrow batches into smaller chunks (controlled by
mc.max_write_batch_rows, default 4096) to avoid HTTP 413 Request Entity Too
Large errors from MaxCompute Storage API.
- Skip unnecessary SORT node for static partition INSERT, since all data
goes to a single known partition and no dynamic routing is needed.
- Enable ZSTD compression for Arrow data transfer to reduce network
bandwidth. New catalog properties:
- mc.max_write_batch_rows: max rows per Arrow batch for write (default: 4096)
- mc.max_field_size_bytes: max field size in bytes for write session
(default: 8MB)
