[jira] [Commented] (CASSANDRA-5645) Display PK values along the
header when using EXPAND in cqlsh
[ https://issues.apache.org/jira/browse/CASSANDRA-5645?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13684630#comment-13684630 ]
Michał Michalski commented on CASSANDRA-5645:
---------------------------------------------
After short investigation it seems that it could be very straightforward fix (getting and properly processing primary_key_components from CF layout) _if_ we had KS and CF name accessible via cursor object. Unluckily - it seems we hadn't, so it's necessary to add them there (which, in general, doesn't seem to be a bad idea to me) - CqlResult seems to be a good place to start. However, I'd appreciate any suggestions. Maybe I missed something in existing cursor implementation or is there better approach?

> Issue Type: Improvement

> Follow-up to CASSANDRA-5597 proposed by [~jjordan].
> Currently cqlsh run in vertical mode prints a header like this:
> {noformat}cqlsh> EXPAND on;
> Now printing expanded output
> cqlsh> SELECT * FROM system.schema_columnfamilies limit 1;
> @ Row 1
> -----------------------------+-----------------------------------------------------------------------------------------
> keyspace_name | system_auth
> columnfamily_name | users
> bloom_filter_fp_chance | 0.01
> caching | KEYS_ONLY
> column_aliases | []
> (...){noformat}
> The idea is to make it print header this way:
> {noformat}cqlsh> EXPAND on;
> Now printing expanded output
> cqlsh> SELECT * FROM system.schema_columnfamilies limit 1;
> @ Row 1: system_auth, users
> -----------------------------+-----------------------------------------------------------------------------------------
> keyspace_name | system_auth
> columnfamily_name | users
> bloom_filter_fp_chance | 0.01
> caching | KEYS_ONLY
> column_aliases | []
> (...){noformat}
> [~jjordan], please verify if it's what you requested for.
