Subject [jira] Commented: (AMQ-1762) Field Type for ID column on table activemq_msgs should be increased from integer to bigint for postgres
Date Tue, 07 Sep 2010 08:59:41 GMT

    [ https://issues.apache.org/activemq/browse/AMQ-1762?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=61708#action_61708

Dziugas Baltrunas commented on AMQ-1762:
----------------------------------------

Was this issue fixed in any of 4.1.X or 5.X tree? For systems with some 200 msg / sec throughput,
INTEGER reaches it's boundary in few months, so I believe this problem affects quite a lot
of heavy users. Our workaround was to ALTER TABLE.

> As the postgres size for an int is limited to: 2147483647 you can easily reach that number
on a loaded ActiveMQ server within weeks. This is very hard to nail issue, as you get an exception
like: Batch entry 0 INSERT INTO ACTIVEMQ_MSGS(ID, MSGID_PROD, MSGID_SEQ, CONTAINER, EXPIRATION,
MSG) VALUES (2152101302, ID:cnmacoll2.ms.de.cdip.net-2970-1212478745177-0:1397:1:1, 1, queue://CNMACollector_1000474_1000474,
0, <stream of 820 bytes>) was aborted.
> Which gives you no clue about the real issue, so we searched for all kinds of issues
around. 
> However we figured out it was the ID column.
> Not sure if this happens on other plattforms too, but at least on all PostgreSQL versions.
> While checking this, someone should make sure that not the ID inside the java code will
be the next issue.
