Brandon Williams commented on CASSANDRA-7766:
---------------------------------------------
Haven't been able to reproduce on 2.1.0 head, though I'm not sure how long a
while is. Forcing a flush/compaction doesn't help either.
> Secondary index not working after a while
> -----------------------------------------
>
> Key: CASSANDRA-7766
> URL: https://issues.apache.org/jira/browse/CASSANDRA-7766
> Project: Cassandra
> Issue Type: Bug
> Environment: C* 2.1.0-rc5 with small clusters (one or two nodes)
> Reporter: Fabrice Larcher
> Attachments: result-failure.txt, result-success.txt
>
>
> Since 2.1.0-rc2, it appears that the secondary indexes are not always
> working. Immediately after the INSERT of a row, the index seems to be there.
> But after a while (I do not know when or why), SELECT statements based on any
> secondary index do not return the corresponding row(s) anymore. I noticed
> that a restart of C* may have an impact (the data inserted before the restart
> may be seen through the index, even if it was not returned before the
> restart).
> Here is a use-case example (in order to clarify my request) :
> {code}
> CREATE TABLE IF NOT EXISTS ks.cf ( k int PRIMARY KEY, ind ascii, value text);
> CREATE INDEX IF NOT EXISTS ks_cf_index ON ks.cf(ind);
> INSERT INTO ks.cf (k, ind, value) VALUES (1, 'toto', 'Hello');
> SELECT * FROM ks.cf WHERE ind = 'toto'; // Returns no result after a while
> {code}
> The last SELECT statement may or may not return a row depending on the
> instant of the request. I experienced that with 2.1.0-rc5 through CQLSH with
> clusters of one and two nodes. Since it depends on the instant of the
> request, I am not able to deliver any way to reproduce that systematically
> (It appears to be linked with some scheduled job inside C*).
