Subject [jira] [Commented] (CASSANDRA-8869) Normalize prepared query text
Date Thu, 26 Feb 2015 22:26:06 GMT


Jonathan Shook commented on CASSANDRA-8869:

We looked at this in more detail. It initially looked like a trivial change, but after digging
in a bit, there are some potentially thorny issues how it might behave in practice.

For example, if you are using 75% of the allotted space for prepared statement caching, then
it would be possible to seriously impact a production load due to a rolling upgrade churning
the cache.

Fixing this issue might not be worth the risk or even the trouble to log a warning.

> It's possible for equivalent queries with different case and/or whitespace to resolve
to different prepared statement hashes.
