Hi all, The question.
We have Cassandra 3.11.1 with really heavy primary partitions: cfhistograms 95%% is 130+ mb, 95%% cell count is 3.3mln and higher, 98%% partition size is 220+ mb sometimes partitions are 1+ gb. We have regular problems with node lockdowns leading to read request timeouts under read requests load. Changing primary partition key structure is out of question. Are there any sharding techniques available to dilute partitions at level lower than 'select' requests to make read performance better? Without changing read requests syntax? Thank you all in advance, Vsevolod Filaretov.
