[jira] [Updated] (CASSANDRA-4000) Division by zero on get_slice
[ https://issues.apache.org/jira/browse/CASSANDRA-4000?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Sergey B updated CASSANDRA-4000:
--------------------------------
Description:
We have a column family with String row keys and Long column keys.
Our WideEntityService is trying to get the first column in the range from 0 to Long.MAX. It's a batch operation performed for every row in the CF (rows count is approximately tens of thousands and each row contains from 0 to 1000 columns).
After processing each row we are removing some of the columns we have queried. Also, at the same time we are writing in this CF in another threads but somewhat less intensive.
An error rises approximately for a one of 100 rows.
Exception itself:
[05-Mar-2012 18:47:25,247] ERROR [http-8095-1 WideEntityServiceImpl.java:142] - get: key1 - {type=RANGE, start=0, end=9223372036854775807, orderDesc=false, limit=1}
