Hello, I have used C* 2.1.0-rc1, 2.1.0-rc2, 2.1.0-rc3 and I currently use 2.1.0-rc5. Since 2.1.0-rc2, it appears that the secondary indexes are not always working. Just 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) : 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 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*). Is anyone working on this issue ? Am I possibly missing some configuration that prevent secondary indexes to return empty result ? Should I rather create a new table for each secondary index and remove secondary indexes ? Many thanks for your support. Fabrice
