Hi ,
I will try with JMX but I try with tpstats. In tpstats its showing pending
compaction as 0 but in nodetool compactionstats its showing 3. So, for me its
seems strange.

Hi Charulata,
IMO, 64MB is fine unless you archive commit log or scan it for backup.

I have the following schema:
CREATE TABLE total_volume (
team_id text,
channel_id text,
volume counter,
PRIMARY KEY (team_id, channel_id)
);
I've written an integration test, using CassandraUnit, which runs a loop
200 times and executes the query:
UPDATE total_volume SET volume = volume + 1 WHER

Can anyone please tell me the implication of increasing the

Hi Luigi
Under the hood, nodetool is actually just a command line wrapper around
certain JMX calls. If you are looking to automate some more of commonplace
nodetool actions, have a look at the nodetool source and it will show
exactly what JMX calls (and parameters) are being passed.

my cluster is getting bigger and I was looking into automating some tedious

I gave a quick search and I didn't find any good available option, so I

Maybe try to monitor through JMX with
'org.apache.cassandra.db:type=CompactionManager', attribute 'Compactions'
or 'CompactionsSummary'

Obviously "It happened to me in the past in a bad way"*. Thinking faster
than I write... I am quite slow writing :p.
To be clear I recommend:

Hi,
To put it easy, I have been taught that anything that can be disabled is an
optimization. So we don't want to rely an optimization that can silently
fail. This goes for read repair as well as we cannot be sure that all the
data will be read. Plus it is configured to trigger only 10 % of the ti
Hi,
I am not sure about this one. It happened to me in the past as well. I
never really wondered about it as it was gone after a while or a restart
off the top of my head. To get rid of it, a restart might be enough.
But if you feel like troubleshooting this, I think the first thing is to

Hi Pranay,
According to
http://docs.datastax.com/en/cassandra/3.0/cassandra/tools/toolsTPstats.html,
"*MemtableReclaimMemory*" is the thread pool used for "Making unused memory
available". I don't know much about it since it was never an issue for me.
Neither did I heard much about it.

This is very long. Looks like you are having a major issue, and it is not
just about dropping tables... Or is it on happening during drop table
actions? Knowing the complete set of GC options i
