Description
We use CQLSStableWriter to produce testing datasets.
Here are the steps to reproduce this issue :
1) definition of a table with counter
CREATE TABLE my_counter ( my_id text, my_counter counter, PRIMARY KEY (my_id) )
2) with CQLSSTableWriter initialize this table (about 2millions entries) with this insert order (one insert / key only)
UPDATE myks.my_counter SET my_counter = my_counter + ? WHERE my_id = ?
3) load the files written by CQLSSTableWriter with sstableloader in your cassandra cluster (tested on a single node and a 3 nodes cluster)
4) start a process that updates the counters (we used 3millions entries distributed on the key my_id)
5) after a while try to query a key in the my_counter table
cqlsh:myks> select * from my_counter where my_id='0000001';
Request did not complete within rpc_timeout.
