Alex Petrov updated CASSANDRA-11990:
------------------------------------
Reviewer: Sam Tunnicliffe
Status: Patch Available (was: Open)
I've tested random partitioner and it (mostly) works, although as suggested I'd
highly advise bringing in support for different partitioners for the next
patch. Reason for leaving the random partitioner out is that the test suite
will require quite some refactoring, and current patch is already quite big.
I've implemented a serialization helper that abstracts all the logic that will
be required to implement a fixed-size token reading. For variable-size token
reading we'll have to invest some more work and implement skipping in some
reasonable way.
I've implemented the support for reading from old format (ab). Although to make
the testing more complete, I'm going to be working on the upgrade tests for
SASI. Also, dtests are missing for SASI, so I'll create a ticket for that.

> Currently, the lookup in SASI index would return the key position of the
> partition. After the partition lookup, the rows are iterated and the
> operators are applied in order to filter out ones that do not match.
> bq. TokenTree which accepts variable size keys (such would enable different
> partitioners, collections support, primary key indexing etc.),
