pyarrow.decompress

pyarrow.decompress(buf, decompressed_size=None, codec=u'lz4', asbytes=False, memory_pool=None)

Decompress data from buffer-like object.

Parameters:

• buf (pyarrow.Buffer, bytes, or memoryview-compatible object) –
• decompressed_size (int64_t, default None) – If not specified, will be computed if the codec is able to determine the uncompressed buffer size
• codec (string, default 'lz4') – Compression codec. Supported types: {‘brotli, ‘gzip’, ‘lz4’, ‘snappy’, ‘zstd’}
• asbytes (boolean, default False) – Return result as Python bytes object, otherwise Buffer
• memory_pool (MemoryPool, default None) – Memory pool to use for buffer allocations, if any

Returns:

uncompressed (pyarrow.Buffer or bytes (if asbytes=True))
