[teiid-issues] [JBoss JIRA] (TEIID-4489) Adjust defaults and use of 1 to 10 data sources to recommend the SMALL size

[Van Halbert (JIRA)]

    [ https://issues.jboss.org/browse/TEIID-4489?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13344216#comment-13344216 ] 

Van Halbert commented on TEIID-4489:
------------------------------------

Couple of comments:

-  we don't recommend the number of DV instances based on number of cores, and therefore implying, only use one big machine.    
-  using # of data sources of 5 will indicate to have 16GB JVM memory.  However, just change Use Cloud to true, and that jvm recommendation changes to 6GB.  I find it hard to believe that with all things being equal, the JVM would be reduced for the cloud use.     This is where indicating the number of DV instances might be needed.

> Based on recommendations:
> small :  16 cores, with at least 32 GB RAM. 2 DV instances.  (small means may be 5 ~10 sources, rows into millions, YMMV)
> medium : 32 cores with 64 GB RAM, 4 DV instances. (medium means may be 10 ~ 20 sources, rows into multi-millions, YMMV)
> Large: custom
> The defaults in the sizing applications, along with selecting 1 to 10 data sources, should result in the SMALL recommendation.  It should be clear to indicate the number of instances and the size recommendation per instance.
