James Taylor commented on PHOENIX-154:
--------------------------------------
For (1), you need to confirm whether or not Apache Calcite supports the syntax
you're proposing as that's a prerequisite. If they don't, then you need to work
with the syntax they have.
I'm not sure I follow (2). Assuming the rows are ordered by the partition key,
why wouldn't sliding windows help? Probably best to comment directly on
PHOENIX-2700 and write the query you think will express what we want to do (and
we can further discuss there).
For (3), no, it'd need to work across the multiple region servers (that's kind
of the point). You can do work on the client as well (that's how we support
aggregation).
