[jira] Commented: (AVRO-91) add json codec in python

["Doug Cutting (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/AVRO-91?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12750022#action_12750022 ] 

Doug Cutting commented on AVRO-91:
----------------------------------

> One drawback of having {read,write}{Record,Union}{Start,End} methods is that all clients that use decoder/encoder
> will have to generate these calls. This could be cumbersome for the clients and/or have performance impact.

There are not many clients.  Mostly it's just generic, since specific inherits from that, no?  So this is only a problem if we expect applications to code directly to the Encoder/Decoder API.  The Java parser was implemented with that in mind, so that folks could, e.g., write data in a streaming manner, without ever building objects.  Do we expect folks to do this much in Python?

As for performance, I would not expect two no-op method calls per record and union would impact things much.
