Subject [jira] [Commented] (CASSANDRA-2478) Custom CQL protocol/transport
Date Fri, 25 May 2012 19:34:23 GMT


Rick Shaw commented on CASSANDRA-2478:

Much of the pressure in the corporate world I live in is from teams that are trying to use
JDBC driver for C* in the same fashion and with the same BI, ETL  and statistics tools (Talend,
Informatica, Datastage, SPSS, SAS) as they do for relational solutions. Many of these tools
are quite comprehensive in the information they can display and use, so they are heavy users
of the metadata features of the driver. Returning no data for some functions often causes
the tooling to just give up, not to use what they have.

> A custom wire protocol would give us the flexibility to optimize for our specific use-cases,
and eliminate a troublesome dependency (I'm referring to Thrift, but none of the others would
be significantly better).  Additionally, RPC is bad fit here, and we'd do better to move in
the direction of something that natively supports streaming.
> I don't think this is as daunting as it might seem initially.  Utilizing an existing
server framework like Netty, combined with some copy-and-paste of bits from other FLOSS projects
would probably get us 80% of the way there.
