Subject [jira] [Commented] (CASSANDRA-3010) Java CQL command-line shell
Date Wed, 10 Aug 2011 15:33:29 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-3010?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13082402#comment-13082402
] 

Jonathan Ellis commented on CASSANDRA-3010:
-------------------------------------------

bq. Is this syntax going to be available to clients of CQL queries at run time, or is this
just a CLI grammar addition? 

The latter.  (Which matches every other language + db shell combination I have seen.)

bq. I believe the functionality of the "describe" needs to be available at runtime. 

Agreed, but not by adding extra syntax to CQL itself (CASSANDRA-2477).

bq. By "cli", do you mean "cqlsh"? If not, how will a CQL shell avoid breaking scripts that
use the cli's syntax?

That was my way of saying "we should make a new tool, and leave the existing cli alone for
backwards compatibility."

> We need a "real" CQL shell that:
> - does not require installing additional environments
> - includes "show keyspaces" and other introspection tools
> - does not break existing cli scripts
> I.e., it needs to be java, but it should be a new tool instead of replacing the existing
cli.
