Subject [jira] [Commented] (CASSANDRA-2780) sstable2json needs to escape quotes
Date Thu, 16 Jun 2011 23:43:47 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-2780?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13050811#comment-13050811
] 

Brandon Williams commented on CASSANDRA-2780:
---------------------------------------------

{quote}
So using a JSON generator / writer would make sense, if project uses one already? If not,
I would recommend adding handling of backslashes and white space other than space (char codes
below 32), as those must be escaped in String values and keys.
{quote}

We don't use one.  I believe the historical reason is that one couldn't be found that would
handle things incrementally, but I think that may have changed by now (sst2j is pretty long
in the tooth) and we should probably switch to one if possible.
