------------------------------------
Summary: cqlsh: interpret CQL type for formatting blobs
Key: CASSANDRA-11274
URL: https://issues.apache.org/jira/browse/CASSANDRA-11274
Project: Cassandra
Issue Type: Improvement
Components: Tools
Reporter: Stefania
Assignee: Stefania
Fix For: 3.x
During the development of CASSANDRA-11053 we have added changes to the cqlsh
formatting code so that we can format {{blob}} types correctly even if they are
represented as {{str}} rather than {{bytearray}}.
At the moment we ensure {{blob}} are of type {{bytearray}} via the following
trick:
{code}
cassandra.cqltypes.BytesType.deserialize = staticmethod(lambda byts,
protocol_version: bytearray(byts))
{code}
After CASSANDRA-11053 is committed there will be a similar trick to override
the fast serializers implemented in cython. This trick was not known initially,
which is why the code to interpret CQL types was written.
Decoding the CQL type is safer in that it decouples cqlsh formatting from the
types returned by the driver deserializers but it is also unnecessary for
CASSANDRA-11053 performance goals and risky for older releases.
Therefore this ticket delivers this functionality but only on trunk.
