Subject [jira] [Updated] (CASSANDRA-11274) cqlsh: interpret CQL type for formatting blob types
Date Mon, 29 Feb 2016 05:47:18 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-11274?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Stefania updated CASSANDRA-11274:
---------------------------------
    Description: 
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 shortcut:

{code}
cassandra.cqltypes.BytesType.deserialize = staticmethod(lambda byts, protocol_version: bytearray(byts))
{code}

After CASSANDRA-11053 is committed there will be a similar shortcut to override the fast serializers
implemented in cython. 

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.

After CASSANDRA-11053 is committed there will be a similar shortcut 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.

by the driver deserializers but it is also unnecessary for CASSANDRA-11053 performance goals
and risky for older releases.
