sankalp kohli commented on CASSANDRA-12106:
-------------------------------------------
The patch which we will contribute for IndexInfo makes it better but we will
still need a limit on partition sizes. I agree we cannot keep adding features
to Cassandra but this is the top requested feature we get from ops teams. I
guess thats why we have features like large batch rejection, CASSANDRA-8303,
CASSANDRA-9318, etc.
We can see how we can simplify the implementation. Since we need to reject
requests, we will need to keep it in memory and hence the cache. Regarding
keeping this cache b/w co-ordinator and replicas, we chose replica since it is
more efficient to keep it there since this list can grow and we want to reduce
the things in memory.
> Add ability to blacklist a CQL partition so all requests are ignored

> Sometimes reads/writes to a given partition may cause problems due to the
> data present. It would be useful to have a manual way to blacklist such
> partitions so all read and write requests to them are rejected.
