On this page at last, there's a note about Major Compaction which says, Also, once you run a major compaction, automatic minor compactions are no > longer triggered frequently... Could anybody give an explanation for that, because as far as I think, once a major compaction takes place, after that let's say there would be no compactions till N(default value 4) SSTables of same size (size of memtable to be precise) are formed, then automatically minor compactions would start. Is the author referring to this time period as no minor compactions being triggered automatically ? Also, I want to make sure, if Major compactions could only be done manually ? -- *Rajat Mathur*
