Problem with sql_range_partitions #49

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago
Which version of common_schema are you using? 
2.2

Which component is failing? 
sql_range_partitions

What is the expected output? What do you see instead?
I expected an output with count_past_partitions, count_future_partitions and 
sql_add_next_partition filled, because we have some tables created with range 
partitions for every month since 2009-01-01, two partitions for the years 
before and one with maxvalue. The partitions have been limited by to_days().
Instead of this expection, the output shows null for these three columns.

Can you provide with sample data?
Here is a shortened output of SHOW CREATE TABLE:
CREATE TABLE `receipt_line` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `receipt_id` int(11) unsigned DEFAULT NULL,
  `status` char(1) COLLATE utf8_unicode_ci DEFAULT NULL,
  `receipt_date` date NOT NULL,
  `product_id` int(11) DEFAULT NULL,
  `data_status` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
  PRIMARY KEY (`id`,`receipt_date`),
) ENGINE=InnoDB AUTO_INCREMENT=46694279 DEFAULT CHARSET=utf8 
COLLATE=utf8_unicode_ci PACK_KEYS=1 DELAY_KEY_WRITE=1

GoogleCodeExporter commented 9 years ago
"This view auto-deduces the "next in sequence" partition value. It handles 
consistent partitioning schemes, where the interval of values between 
partitions makes some sense. Such an interval can be a constant value, but can 
also be a time-based interval. "

The problem here is that there is an inconsistent interval within your 
partitions: at first there's a full year, then followed by a single month 
scheme.
At this time, this view only handles fully consistent schemes; there's a TODO 
to review the last n partitions and ignore old ones, to handle the exact 
scenario you describe.
