John Sichi updated HIVE-417:
----------------------------
Attachment: idx.png
Attaching metastore data model diagram reverse-engineered from Yongqiang's
latest patch (using Power Architect); can be used in a design doc. Cosmetic:
I renamed INDEXS to IDXS for consistency with TBLS, likewise for IDX_ID and
other attributes.
I marked one of the relationships between index and table as optional since we
want to allow for indexes which don't store their data structure in tabular
form. I'm not sure whether there's something we need to do in package.jdo to
make sure the corresponding key is nullable.
