[jira] [Commented] (AVRO-2796) Generated schema class can't be compiled: code too large

["Christophe Le Saec (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/AVRO-2796?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17574719#comment-17574719 ] 

Christophe Le Saec commented on AVRO-2796:
------------------------------------------

Model on [^record.avsc] sounds tricky. [^recordfixed.avsc] model just replaces long lists of fields like "prop1", "prop2" ... "prop100" ... by one field props that is an array of ... And it's enough to make it works. No needs to have sub-records like "mobile", "city" ... even if it could be better with.

So, what about closing this ticket ?
