Does TWCS uses only these two parameters of STCS (min and max threshold) or
uses all the STSC parameters?

the compaction.log data (in
Json format).
These info you gave will be very useful to me. Hope it can get into the
documentation.

Good answer Oleksandr,
But I think the data is inserted in the Memtable already in the right
order. At least the datastax academy videos say so.
But it shouldn't make any difference anyhow.
Kind regards,

know what it is but surely is not the amount of

Dear community,
I want to tell you about my paper published in a conference in March. The
title is " NoSQL Database Performance Tuning for IoT Data - Cassandra Case
Study" and it is available (not for free) in
http://www.scitepress.org/DigitalLibrary/Link.aspx?doi=10.5220/0006782702770284

Yes, but remind that there is Write Consistency and Read Consistency.
To prevent the reads from reaching the other DC, you should set the Read
Consistency LOCAL_ONE.
As Hannu Kroger said, the LOCAL_ONE may be enough to you but maybe not if
you want to be sure that your data was written also in

Hello Ahmed,
I have questioned about the compaction metrics in 27/10/2017.

Although it is not proven that the same results will persist in different

I don't know if it you help you, but when the debug log is turned on, it
displays the slow queries.
To consider slow, the parameter read_request_timeout_in_ms is considered.
Maybe if you decrease it, you can monitor your queries, with $tail -F
debug.log
Just an idea, I've never made it. Surely
threads.

and a prometheus client).
When I run netstat -na it does not show port 7199 open.
Tried to look at the logs but didn't see anything.
Can you figure out why it happened and point any possible solution? Config
files enable JMX with authtenticaion=false, but it doesn't work.
Thanks in advance,
Lucas
