[jira] [Commented] (THRIFT-2063) Go compiler cannot create code for maps with a map as key

["Aleksey Pesternikov (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/THRIFT-2063?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13813015#comment-13813015 ] 

Aleksey Pesternikov commented on THRIFT-2063:
---------------------------------------------

Cassandra and Hbase interfaces would compile and work if binary keys are implemented as strings (actually working in this fork https://github.com/apesternikov/thrift4go). 
Implementing custom keys (as in https://github.com/pomack/thrift4go) makes the code non-typesafe, much less efficient and produces unreadable interface.
