[jira] [Commented] (ASTERIXDB-1099) Format printers may have multi-threading errors

["Till Westmann (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ASTERIXDB-1099?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14791148#comment-14791148 ] 

Till Westmann commented on ASTERIXDB-1099:
------------------------------------------

And it does have state. It seems to me that the right approach to fix this would be to to have one printer per thread (and not to synchronize then).
Would you agree?

> Several of the printers - for instance, org.apache.asterix.dataflow.data.nontagged.printers.AUUIDPrinter - have a static member which is used for formatting the data. This static member would be shared by any threads on the NC and is not synchronized, so there is at least the possibility of data corruption.
