5 provide compression and decompression features and it is based on deflate
6 compression algorithm (RFC 1951).
8 The ``QPL`` compression relies on Intel In-Memory Analytics Accelerator(``IAA``)
115 - 8 engines and 1 work queue are configured in group 0, so all compression jobs
163 The multifd migration with ``QPL`` compression method  will use all work
204 4 - Enable ``QPL`` compression during migration
206   Set ``migrate_set_parameter multifd-compression qpl`` when migrating, the
207   ``QPL`` compression does not support configuring the compression level, it
208   only supports one compression level.
213 Although both ``QPL`` and ``ZLIB`` are based on the deflate compression
215 is still not fully compatible with the ``ZLIB`` compression in the migration.
222 compression, current ``ZLIB`` implementation uses ``Z_SYNC_FLUSH``, so each
223 ``multifd`` thread has a ``ZLIB`` streaming context, and all page compression
232 When user enables the IAA device for ``QPL`` compression, it is recommended
235 of IAA compression and decompression.
