Subject [jira] [Updated] (CASSANDRA-3726) cqlsh and cassandra-cli show keys differently for data created via stress tool
Date Thu, 19 Jan 2012 16:53:40 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-3726?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

paul cannon updated CASSANDRA-3726:
-----------------------------------

    Attachment: 3726.patch.txt

Added a bunch to cqlsh's output formatting so that certain types (in particular, blob) are
shown in a more human-readable way. Used colors (when enabled) to help distinguish hex strings
from text strings, and to distinguish control characters in text strings.

The attached patch contains the changes, or the 3726 branch in my github fork can be used:
