Project: Hive
Issue Type: Bug
Reporter: Sergey Shelukhin
The JSON can be too big with many columns.
We can make JSON more compact by only storing the list of columns with true
values. Or we can even store a bitmask in a dedicated column, and adjust it
when altering table (rare enough). Or we can just change the VALUE column to
text blob (might be a painful change wrt upgrade scripts, and supporting all
the DBs' varied blob implementations, esp. in directsql).
Storing denormalized flags in a separate table will probably be slow,
comparatively.
