Hi William,


It's probably what I have looked for, thus I will try soon. Thank you!

Swap out 1.5 in the previous link for the version you're probably using.

Which charts are you looking at for the compactions? Usually it's just the number of compactions
currently running for the system.

for minor compacting (aka "flushing") a table via the API.

Hi,


Please share with me is there any way that we can init / control the Minor Compaction by programming
(not from the shell). My situation is when I ingest a large data using the BatchWriter, the
minor compaction is triggered uncontrollably. The flush() command in BatchWriter seems not
for this purpose.

I also tried to play around with parameters in documentation but seems not much helpful.


Also, can you please explain the number 0, 1.0, 2.0, ... in charts (web monitoring) denoting
the level of Minor Compaction and Major Compaction?


Thank you!

Hai Pham
