Anoop Sam John commented on HBASE-24378:
----------------------------------------

We have another size based config to decide whether to cache the compacted data or not right?  So what u suggest is a new boolean config (applicable for DTC) and if that is false, we will never cache compacted file data on write. If that is true, we will consider it for caching but the size check again will happen.  Am I correct?

> In Date tiered compaction once we move to old window - we should ideally not cache the resultant file because generally those files are not read (as it is not the window of our interest). We can provide a switch to either turn it ON or OFF. Preferrably for Data tiered compaction this switch should be OFF.
