Subject [jira] [Commented] (CASSANDRA-2888) CQL support for JDBC DatabaseMetaData
Date Tue, 12 Jul 2011 22:53:00 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-2888?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13064216#comment-13064216

Rick Shaw commented on CASSANDRA-2888:
--------------------------------------

Right now (1.0.4-SNAPSHOT) we just return NULL for this call. Please be specific as to what
you think is REQUIRED to work with your toolset (What is it BTW?) and we can look into providing
a simplistic sparse implementation of static items. I believe the dynamic stuff is way beyond
the scope of what can be done in the midst of the other items in the roadmap for 1.1. We can
tackle the dynamic stuff when CQL decides how it will format the data in a structured ({{CQLResult}})
response.

be updated to include at least semi-valid responses to the JDBC metadata portion.
