Subject [jira] [Commented] (CASSANDRA-4785) Secondary Index Sporadically Doesn't Return Rows
Date Wed, 13 Feb 2013 16:52:13 GMT


André Cruz commented on CASSANDRA-4785:

Bug #5225 mentions RuntimeExceptions and CorruptSSTableExceptions, which does not happen to
me. This CF in particular is smallish (20k rows, 6MB total), so wide rows seem unlikely. 

Also it seems related to 1.2 and my cluster is on 1.1.5 still.

> I have a ColumnFamily with caching = ALL. I have 2 secondary indexes on it. I have noticed
if I query using the secondary index in the where clause, sometimes I get the results and
sometimes I don't. Until 2 weeks ago, the caching option on this CF was set to NONE. So, I
suspect something happened in secondary index caching scheme. 
> Here are things I tried:
> 1. I rebuild indexes for that CF on all nodes;
> 2. I set the caching to KEYS_ONLY and rebuild the index again;
> 3. I set the caching to NONE and rebuild the index again;
> None of the above helped. I suppose the caching still exists as this behavior looks like
cache mistmatch.
> I did a bit research, and found CASSANDRA-4197 that could be related.
> Please advice.
