Manual:image_comment_temp table
| MediaWiki versions: | 1.30 – 1.31 |
Temporary table creating a relation between each row of the image table and a row of the comment table. It has been created to avoid blocking on an alter of the image table. On large wikis like Wikimedia Commons, altering the image table is a months-long process. This table is being created to avoid such an alter, and will be merged back into the image in the future.
This table was introduced in Gerrit change 357892. See also the revision_comment_temp table.
In MediaWiki 1.32, the image_comment_temp table is merged into the image table with T188132. After that, the image_comment_temp table is removed.
