Compression filter for outgoing data.
See <grpc/compression.h> for the available compression settings.
Compression settings may come from:
- Channel configuration, as established at channel creation time.
- The metadata accompanying the outgoing data to be compressed. This is taken as a request only. We may choose not to honor it. The metadata key is given by GRPC_COMPRESSION_REQUEST_ALGORITHM_MD_KEY.
Compression can be disabled for concrete messages (for instance in order to prevent CRIME/BEAST type attacks) by having the GRPC_WRITE_NO_COMPRESS set in the BEGIN_MESSAGE flags.
The attempted compression mechanism is added to the resulting initial metadata under the'grpc-encoding' key.
If compression is actually performed, BEGIN_MESSAGE's flag is modified to incorporate GRPC_WRITE_INTERNAL_COMPRESS. Otherwise, and regardless of the aforementioned 'grpc-encoding' metadata value, data will pass through uncompressed.
