Subject [jira] [Resolved] (CASSANDRA-4330) cqlsh's desc cluster needs to return the schema agreement information
Date Wed, 11 Jul 2012 21:31:35 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-4330?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

paul cannon resolved CASSANDRA-4330.
------------------------------------

    Resolution: Won't Fix

Turns out this is not of much use in 1.1, post "schema renaissance", and the information is
no longer in the system.Schema table (since the system.schema_* tables are now canonical),
so we can't do it via plain CQL. Cqlsh does still use thrift for certain things, but I'd like
to move toward eliminating those, rather than adding to it just for 1.0 when cassandra-cli
can meet the need acceptably.

http://www.datastax.com/dev/blog/the-schema-management-renaissance has good explanations of
the changes.

> describe cluster in the cassandra cli is very useful to determine whether the schema
for the cluster is in complete agreement among the nodes.  It doesn't appear that the cqlsh
analog - desc cluster; - does the same thing.
> Since that's so useful and since cqlsh is the way forward for new cli type of development,
it makes sense to add that in some command in cqlsh.  Paul said that it should be trivial
but if it's not, it may be worth it to wait until the dedicated cql transport to implement
it (while it's still there in cassandra-cli).
