> It is supposed to be - https://arrow.apache.org/docs/format/Columnar.html#buffer-alignment-and-padding by ensuring the buffers are padded correctly, we can ensure that correctly aligning the entire memory allocation is sufficient to align the child allocations. When the writer has not done this correctly, we will have to copy the buffers or return an error. > > > How it can be? That's said we allocate a 80 bytes memory allocation for all buffers containing 1 Int32Array (40 bytes) and and 1 Decimal128Array (32 bytes) and 1 Int32Array (8 bytes). When we try to create array for the Decimal128Array, it takes the slice buffer offset by 40 to 80. Then it will fails at `align_offset` as it is not aligned with i128 (16 bytes). -- This is an automated message from the Apache Git Service.
