[jira] [Commented] (PHOENIX-3547) Promote CATALOG.VIEW_INDEX_ID to
an int
[ https://issues.apache.org/jira/browse/PHOENIX-3547?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15780978#comment-15780978 ]
Jeremy Huffman commented on PHOENIX-3547:
-----------------------------------------
I'm willing to work on this but it is not obvious to me how to achieve the backward compatibility requirement. It looks like there is no field separator between the VIEW_INDEX_ID and the TENANT_ID in the row key prefix, so I'm not sure how to determine the length of the VIEW_INDEX_ID used in any particular index record. Any suggestion here?

> Key: PHOENIX-3547
> URL: https://issues.apache.org/jira/browse/PHOENIX-3547
> Project: Phoenix
> Issue Type: New Feature
> Reporter: Jeremy Huffman
> Priority: Minor
>
> Increase the size of CATALOG.VIEW_INDEX_ID from smallint to int to support a large number of indexed views on a single table.
> Per James: "The code would just need to be tolerant when reading the data if the length is two byte short versus four byte int. At write time, we'd just always write an int."
