Subject [jira] [Commented] (FLINK-6983) Do not serialize States with NFA
Date Thu, 22 Jun 2017 08:10:00 GMT

    [ https://issues.apache.org/jira/browse/FLINK-6983?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16058959#comment-16058959

Dawid Wysakowicz commented on FLINK-6983:
-----------------------------------------

I agree that getting states by name would be the way to go, but it may happen that after a
change partial matches could be no longer valid for new graph of states. Also the versioning
of `SharedBuffer` is pretty fragile and after a graph is changed there may be some paths collisions
which can result in incorrect matches.

For the second part, rather than changing an NFA, we would like to have multiple NFAs, that
may be injected in runtime. I think the new ValueState would end up to be equal to NFA itself,
cause we would need to move {{State}}s, {{ComputationState}}s and {{SharedBuffer}} there ;)
