Subject [jira] [Resolved] (CASSANDRA-9705) Simplify some of 8099's concrete implementations

Sylvain Lebresne resolved CASSANDRA-9705.
-----------------------------------------
    Resolution: Fixed

Yes, there were a few small problems with reading old sstables. I should have run those tests
but I forgot sorry. Anyway, took the liberty to directly fix those in commit [f713be4a|https://git1-us-west.apache.org/repos/asf?p=cassandra.git;a=commitdiff;h=f713be4a],
so closing again (if you still find upgrade tests that are broken, feel free to re-open, but
in that case please point me to which test is failing exactly cause the upgrade tests I've
used are all passing).

> As mentioned in the ticket comments, some of the concrete implementations (for Cell,
Row, Clustering, PartitionUpdate, ...) of the initial patch for CASSANDRA-8099 are more complex
than they should be (the use of flyweight is typically probably ill-fitted), which probably
has performance consequence. This ticket is to track the refactoring/simplifying those implementation
(mainly by removing the use of flyweights and simplifying accordingly).
