fix: Honor useUnalignedBuffers in ArrowReader.readStreaming#179
Merged
Conversation
readStreaming declared a useUnalignedBuffers parameter and ignored it, hardcoding allowReadingUnalignedBuffers: true when constructing the ByteBuffer. Forward the caller's value instead, matching readFile and fromMessage, which already do so. No new test is included: the flag selects between aligned and unaligned loads inside FlatBuffers and does not change the result of any read on this path, since ByteBuffer(data:) copies the input into aligned storage. A test exercising the parameter would pass with and without this change. Closes apache#177

The full test suite passes with this change.
No new test is included: the flag selects between aligned and unaligned
loads inside FlatBuffers and does not affect the result of any read on this
path, because
ByteBuffer(data:)copies the input into aligned storage. Atest exercising the parameter would pass both with and without this change,
so it would not guard against a regression.
