James Taylor commented on PHOENIX-2795: --------------------------------------- +1. Looks great - thanks, [~tdsilva]. > Support auto partition for views > -------------------------------- > > Key: PHOENIX-2795 > URL: https://issues.apache.org/jira/browse/PHOENIX-2795 > Project: Phoenix > Issue Type: Sub-task > Reporter: James Taylor > Assignee: Thomas D'Silva > Labels: argus > Fix For: 4.8.0 > > Attachments: PHOENIX-2795-v2.patch, PHOENIX-2795-v3.patch, > PHOENIX-2795.patch > > > 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: > {code} > WHERE partition_id = NEXT VALUE FROM metric_id_seq > {code} > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
