Subject [jira] [Commented] (CASSANDRA-13701) Lower default num_tokens
Date Fri, 21 Jul 2017 01:25:01 GMT


Jeremy Hanna commented on CASSANDRA-13701:

Adding datacenters with the new algorithm requires some additional configuration.  We would
need to make users aware of that trade-off when using that algorithm and the benefits of fewer
token ranges per node.  It's talked about [here|]
but we should make it clearer in the apache docs as well.  We can point to those in the comments
around vnode tokens.

It is very expensive for operations processes and scanning. Its come up a lot and its pretty
standard and known now to always reduce the num_tokens within the community. We should just
lower the defaults.
