This patch implement initial support for CQL binary protocol versions 1,
2, 3, and 4. The CQL server is able to handshake with cqlsh and
cassandra-stress from Cassandra 2.1 which uses the STARTUP and OPTIONS
messages. Queries or other functionality is not supported.
To try it out, start Urchin:
$ build/release/seastar --smp 1 --datadir data
CQL server listening on port 9042 ...
Thrift server listening on port 9160 ...
Then try to login with cqlsh:
$ ./bin/cqlsh 127.0.0.1
Urchin side will fail with:
CQL_VERSION => 3.2.0
warning: ignoring event registration
warning: ignoring query SELECT peer, data_center, rack, tokens, rpc_address, schema_version FROM system.peers
seastar: cql/server.cc:222: future<> cql_server::connection::process_query(uint16_t, temporary_buffer<char>&): Assertion `0' failed.
Aborted (core dumped)
TODO:
- Compression is not supported.
- Authentication is not supported.
- Supported options are defined to make cqlsh and cassandra-stress
happy. We really need to decide which CQL versions and compression
algorithms we want to support.
- std::string is used everywhere because sstring does not work with
std::map, std::multimap, and others.
