Andres de la Peña commented on CASSANDRA-17698:
-----------------------------------------------
The patch mostly looks good to me. However, it changes the sstables in a way
that breaks backward compatibility. Thus, sstables created with the patched
version would produce a server startup failure with the unpatched version. I
understand that requires [a major sstable version
bump|https://github.com/apache/cassandra/blob/cassandra-4.1.0/src/java/org/apache/cassandra/io/sstable/format/big/BigFormat.java#L124].
Those type of major sstables changes can only be done on major releases. So the
current patch should go in 5.0 only. However, I think we don't have a branch
for 5.0. Instead, the current {{trunk}} branch in for 4.2. It seems that it
will become 5.0 when we have a breaking change that justifies the bump to a
major. That bump to 5.0 is meant to be done in CASSANDRA-17973. See [this mail
list
discussion|https://www.mail-archive.com/[email protected]/msg19516.html]
for context.
{quote}what about just fix this patch (what I will doing some modification
latter for trunk), and left the older branches unchanged?
{quote}
I think we should try to fix the bug for older branches in a way that doesn't
break sstables backward compatibility. Possibly by just JSON-printing the
failing clustering key as raw bytes, [this
way|https://github.com/apache/cassandra/blob/trunk/src/java/org/apache/cassandra/db/marshal/BytesType.java#L70-L73].
If we don't want to do it here we can open a separate ticket and set the fix
version of this ticket as 5.0, making this depend on CASSANDRA-17973.
