Increase size of content_models.model_id
Closed, ResolvedPublic

Description

(Part of T230428: Migrate tables.sql to abstract schema)

  1. ALTERs to run: https://gerrit.wikimedia.org/r/c/mediawiki/core/+/619155/5/maintenance/archives/patch-content_models-model_id.sql
  2. Where to run those changes: all.dblist
  3. When to run those changes: At any time
  4. If the schema change is backwards compatible: Yes
  5. If the schema change has been tested already on some of the test/beta wikis: Tested in beta cluster.
  6. if the data should be made available on the labs replicas and/or dumps: Yes, data in this table is public

This field previously was SMALLINT, it should be INT now.

Event Timeline

LSobanski triaged this task as Medium priority.Dec 14 2020, 10:23 AM
LSobanski moved this task from Triage to Ready on the DBA board.

This schema change cannot be done ONLINE as it changes the datatype of the column. However, the table looks small enough (at least on enwiki) that it can be applied directly on the master with replication enabled.

@Ladsgroup looks good?:

mysql:root@localhost [labtestwiki]> show create table content_models\G
*************************** 1. row ***************************
       Table: content_models
Create Table: CREATE TABLE `content_models` (
  `model_id` int(11) NOT NULL AUTO_INCREMENT,
  `model_name` varbinary(64) NOT NULL,
  PRIMARY KEY (`model_id`),
  UNIQUE KEY `model_name` (`model_name`)
) ENGINE=InnoDB AUTO_INCREMENT=6 DEFAULT CHARSET=binary

Thanks I will deploy it to s6 and let it run for a couple of days to make sure nothing strange comes up.

s6 is done, let's see if we find issues:
