Re: oversized partition detection ? monitoring the partitions growth ?

You can set compaction_large_partition_warning_threshold_mb and alert on
logs

.

Writing large partition {}/{}:{} ({}) to sstable {}

Hi,

I'm not sure that your are able to log which partition has reached 100MB 
but you may monitor the "EstimatedPartitionSizeHistogram"and take the 
max value (or 99ct, 95ct) to trigger an alert using your monitoring system.

how can I detect a partition that reaches the 100MB ? is it possible 
to log the size of every partition one time per day ?

Hi,
how can I detect a partition that reaches the 100MB ? is it possible to log the 
size of every partition one time per day ?
