[jira] [Updated] (CASSANDRA-3289) assert err on
ArrayBackedSortedColumns.addColumn(ArrayBackedSortedColumns.java:126)
[ https://issues.apache.org/jira/browse/CASSANDRA-3289?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jonathan Ellis updated CASSANDRA-3289:
--------------------------------------
Attachment: 3289.txt
collectTimeOrderedData has to use a column store that allows random inserts. Patch attached to use ThreadSafeSortedColumns there, and ArrayBacked for collectAllData.

> then i basically make a call to get key=b with all the column names (yes included column names that didn't exist to save time):
> ColumnFamilyResult<String, String> queryColumns = template.queryColumns("b", Arrays.asList("a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","p","q","r","s","t","u","v","w","x","y","z"));
> (let me know if it would be easier to just upload the sstables to the ticket)
