Subject Re: Can't get performance for scanning the column that is not row key.
Date Tue, 12 Jul 2016 10:01:34 GMT
Wow.

I have cassandra 1.2 and about fifty nodes.


This Cassandra version is no longer supported, 2.0 isn't either and 2.1 is
reaching end of life...

You could use materialised views, SASI indexes or this kind of new
features. Also CQL performances are better in recent versions etc.

You don't expose data about the table you want to read and how you want to
read it, it is hard to tell.

But I am almost sure you could take profit of some new features, bug fixes
and optimisation. Plus I would bet that no one is going to open the
Cassandra 1.2 code anymore to help you. So if you want free or paid
support, go to 2.1 at least, and keep in mind this one is EOL too...

someone advised to read sstables directly. is it helpful?


It would probably be harder than upgrading... And that's what Cassandra
does. I doubt you will be able to do it better than Cassandra does,
excepted, maybe on some rare corner cases...

Good luck,
C*heers,
