Patrick Bannister commented on CASSANDRA-7814:
----------------------------------------------
Is it a requirement that the output of DESCRIBE should sort things
lexicographically? For example, if keyspace test has tables test and users, do
we require that the output of DESCRIBE KEYSPACE test should show the test table
before the users table?
I ask because the dtest for this ticket is very flaky and fails frequently.
It's written to expect a specific sort order in the tables and indexes for the
output of DESCRIBE KEYSPACE. The root cause is in the cassandra Python driver
in cassandra.metadata, because of the implementation of export_as_string() in
the KeyspaceMetadata and TableMetadata classes. They visit their child objects
in the order returned by the Python dict values() function, which is arbitrary
and unsorted.
If lexicographic sorting is a requirement, a modification to the Python driver
will be needed. If lexicographic sorting is not a requirement, then I could
modify the test_describe() dtest to stop caring about the order of objects in
the DESCRIBE output.
This is coming up in CASSANDRA-10190 (adding Python 3 compatibility to cqlsh).
