hellishfire opened a new issue, #88: URL: https://github.com/apache/arrow-java/issues/88
### Describe the bug, including details regarding any error messages, version, and platform. Reproduced on latest arrow release (16.0) When importing a sliced RecordBatch from c to java On c side: ``` auto sliced_record_batch = original_record_batch->Slice(/*offset=*/8, /*length=*/2); arrow::ExportRecordBatch(sliced_record_batch, arrow_array_ptr); ``` On java side: ``` ArrowArray arrowArray = ArrowArray.allocateNew(allocator); Data.importIntoVectorSchemaRoot(allocator, arrowArray, vectorSchemaRoot, null); ``` The imported vectorSchemaRoot maintains the correct length(which is 2), but the offset info (which is 8) is not respected, hence the content of the imported vectorSchemaRoot points to the first 2 rows of the original_record_batch, while the desired content is sliced_record_batch. I'm not familiar with arrow code, but it seems that the offset info is actually present in org.apache.arrow.c.ArrowArray.Snapshot, but org.apache.arrow.c.ArrayImporter ignores the offset in org.apache.arrow.c.ArrayImporter.doImport(ArrowArray.Snapshot) ### Component(s) Java -- This is an automated message from the Apache Git Service.
