Hi Oliver,
I was in a similar situation to you and Matija a few years back as well and
can vouch for what Matija has said. Some data sets are more suitable for
Cassandra than others; so the answer to your question depends on the type
of data and how it is modelled in Cassandra. The data model will

At least set GCGS == max_hint_window_in_ms that way you don't effectively
disable hints for the table while your compaction is running. Might be
preferable to use nodetool garbagecollect if you don't have enough disk
space for a major compaction. Also worth noting you should do a splitting

Same for aggregation, subqueries, etc. And effectively multitable
transactions are out.
If you have simple single-table queries and updates, or can convert the app
to do so, then you're in business.

I was able to overcome the timeout error by setting
memtable_flush_period_in_ms to 0 for all my tables. Initially it was set to
128.
Now I able to write ~4 records/min in cassandra and the script has been
running for around 12 hours now.
However, I am still curious that why was cassandra unabl

Jeff,
Thank you i got this- how about Dropping the existing Tombstones right now
can setting gc_grace time to zero per Table level would be good or what
would you suggest?

Rahul,
Tomstone caused is on the Application driver side so even though they are
not using some of the Columns in their logic
waht they did is that they mentioned in driver logic that means if you are
updateting one Column so the rest of the Columns so the driver automatically
pick some nulls, int
I'll confirm that it's worked for me in the past, but you should always
test changes like this in your lab/qa environment and not rely on some

Then don’t write nulls. That’s the root of the issue. Sometimes they surface
from prepared statements. Othertimes they come because of default null values
