-------------------------------------
Summary: Support auto partition for views
Key: PHOENIX-2795
URL: https://issues.apache.org/jira/browse/PHOENIX-2795
Project: Phoenix
Issue Type: Improvement
Reporter: James Taylor
Assignee: Thomas D'Silva
When a view or base table is created, we should have an string
AUTO_PARTITION_SEQ parameter on CREATE TABLE which uses a sequence based on the
argument on the server side to generate a WHERE clause with the first PK column
and the unique identifier from the sequence.
For example:
{code}
CREATE SEQUENCE metric_id_seq;
CREATE TABLE metric_table (metric_id INTEGER, val DOUBLE)
AUTO_PARTITION_SEQ=metric_id_seq;
CREATE VIEW my_view1 AS SELECT * FROM base_table;
{code}
would tack on a WHERE clause base on the next value in a sequence, logically
like this: {{WHERE partition_id = }} + {{NEXT VALUE FROM}} + {{metric_id_seq}}
It's important that the sequence be generated *after* the check for the
existence of the view so that we don't burn sequence values needlessly if the
view already exists.
