Hi, I am writing this email in order to share the proposal plan for the project to add the compression support to Drizzle Protocol. As I had investigated that only MySQL protocol in Drizzle supports pluggable compression. In Drizzle protocol, right now Brain has only added the ListenDrizzleProtocol class which is basically the alias of ListenMySQLProtocol class. So the basic idea that I have figured out is to add the ClientDrizzleProtocol class into the plugin/drizzle_protocol/drizzle_protocol.h, which is basically the alias of the ClientMySQLProtocol class on the mysql_protocol in order to use the compression over the network in Drizzle protocol. So I can use the ClientMySQLProtocol code as well as permission to use the "plugin/mysql_protocol/net.serv.h" . I will work on the following plugin files plugin/drizzle_protocol/drizzle_protocol.h plugin/drizzle_protocol/drizzle_protocol.cc and takes the reference as plugin/mysql_protocol/mysql_protocol.h plugin/mysql_protocol/mysql_protocol.cc Please correct me if I understand incorrectly. I have a confusion about whats the role of the following below handshake functions /* Handshake packets. */ drizzle_con_set_protocol_version(con, 10); drizzle_con_set_server_version(con, "libdrizzle example 1.2.3"); drizzle_con_set_thread_id(con, 1); drizzle_con_set_scramble(con, (const uint8_t *)"ABCDEFGHIJKLMNOPQRST"); drizzle_con_set_capabilities(con, DRIZZLE_CAPABILITIES_NONE); drizzle_con_set_charset(con, 8); drizzle_con_set_status(con, DRIZZLE_CON_STATUS_NONE); drizzle_con_set_max_packet_size(con, DRIZZLE_MAX_PACKET_SIZE); ret= drizzle_handshake_server_write(con); DRIZZLE_RETURN_CHECK(ret, "drizzle_handshake_server_write", drizzle) ret= drizzle_handshake_client_read(con); DRIZZLE_RETURN_CHECK(ret, "drizzle_handshake_client_read", drizzle); So in capabilities if use the "DRIZZLE_CAPABILITIES_COMPRESS" so it let the server to use the compression. These functions of course use over the network. So my question is that why not to add/enable the DRIZZLE_CAPABILITIES_COMPRESS flag and use the compression/decompression while sending and receive the data. Please clarify me whats the difference in more details?
