Member Function Documentation

◆ get_compressor()

Transaction_compression_ctx::Compressor_ptr_t Transaction_compression_ctx::get_compressor ( THD session)

Return the compressor.

This constructs the compressor on the first invocation and returns the same compressor on subsequent invocations.

◆ managed_buffer_sequence()

Transaction_compression_ctx::Managed_buffer_sequence_t & Transaction_compression_ctx::managed_buffer_sequence ( )

Return reference to the buffer sequence holding compressed bytes.
