Subject [jira] [Commented] (PHOENIX-5084) Changes from Transactional Tables are not visible to query in different client
Date Tue, 01 Jan 2019 23:39:00 GMT

    [ https://issues.apache.org/jira/browse/PHOENIX-5084?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16731710#comment-16731710
] 

Thomas D'Silva commented on PHOENIX-5084:
-----------------------------------------

I used {{PhoenixRuntime.getTableNoCache}} instead of  {{PhoenixRuntime.getTable}} because
previously we were always running a query on {{SYSTEM.CATALOG}}.  {{PhoenixRuntime.getTable}}
will always returned the cached table (if present) which is different behavior than how tables
are resolved while running queries (see PHOENIX-4475 to fix this).

> Scenario:
> # Upsert and commit some data into a transactional table. (Autocommit or following by
explicit commit)
> # Query same table from another client
> The first query on the other client will not see the newly upserted/committed data (regardless
of how long one waits).
> A second identical query will see the new data.
> This happens with both Omid and Tephra.
> I guess we can't write a test for this, since it requires multiple JVMs.
