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:
