Ugh, for the test I just realized that sstableloader probably wont' produce
buckets corresponding with the actual insertion time of the data in twcs.
Well, we can still run the test.

Yes, this used to
I suspect this will work, yes
(Sorry I can't make a proper upgrade path, sorta out of my hands)

Oops, I think the getName() is an important thing:
package com.jeffjirsa.cassandra.db.compaction;
import org.apache.cassandra.db.ColumnFamilyStore;
import java.util.Map;
public class TimeWindowCompactionStrategy extends
org.apache.cassandra.db.compaction.TimeWindowCompactionStrategy {
Or can we just do this safely in a side jar?
package com.jeffjirsa.cassandra.db.compaction;
import org.apache.cassandra.db.ColumnFamilyStore;
import org.apache.cassandra.db.compaction.TimeWindowCompactionStrategy;
import java.util.Map;
public class TimeWindowCompactionStrategy extends
So IF that delegate class would work:
1) create jar with the delegate class
2) deploy jar along with upgrade on node
3) once all nodes are upgraded, issue ALTER to change to the
org.apache.cassandra TWCS class.
will that trigger full recompaction?

For example (delegating all public methods from AbstractCompactionStrategy
and some from TimeWindowCompactionStrategy EXCEPT getName() )
package com.jeffjirsa.cassandra.db.compaction;
public class TimeWindowCompactionStrategy extends AbstractCompactionStrategy
{
Is this still the official answer on TWCS 2.X --> 3.X upgrades? Pull the
code and recompile as a different package?
Can I just declare the necessary class and package namespace and delegate
to the actual main-codebase class?

That wasn't horrible at all. After testing, provided all goes well I can
submit this back to the main TWCS repo if you think it's worth it.
Either way do you mind just reviewing briefly for obvious mistakes?

I hope I can do as you suggest and leapfrog to 3.11 rather than two
stepping it from 3.7->3.11
Just having TWCS has saved me lots of hassle so it’s all good, thanks for
all you do for our community.

I'm sincerely sorry for the hassle, but for various reasons beyond, it's
unlikely I'll update my repo (at least me, personally). One fix is likely
to grab the actual java classes from the apache repo, pull them in and fix
the package names, and compile (essentially making your own 3.11 branch).
I
you are right, it won't even compile:
[INFO] -
[ERROR] COMPILATION ERROR :
[INFO] -
[ERROR]
There’s a chance it will fail to work - possible method signatures changed
between 3.0 and 3.11. Try it in a test cluster before prod

Nevermind, I spoke to quickly. I can change the cass version in the
pom.xml and re compile, thanks!

Easiest approach is to build the 3.11 jar from my repo, upgrade, then ALTER
table to use the official TWCS (org.apache.cassandra) jar
Sorry for the headache. I hope I have a 3.11 branch for you.

Hi all, we're planning an upgrade from 2.1.5->3.11.3 and currently we have
several column families configured with twcs class
'com.jeffjirsa.cassandra.db.compaction.TimeWindowCompactionStrategy' and
with 3.11.3 we need to set it to 'TimeWindowCompactionStrategy'
Is that a safe operation? Will
