* MM-45956: Optimize FileInfo stats query We Denormalize Post.ChannelId on FileInfo.ChannelId ```release-note The file info stats query is now optimized by denormalizing the channelID column into the table itself. This will speed up the query to get the file count for a channel on clicking the RHS. Migration times: On a MySQL 8.0.31 DB with 1405 rows in FileInfo and 11M posts, it took around 0.3s On a Postgres 12.14 DB with 1731 rows in FileInfo and 11M posts, it took around 0.27s ``` https://mattermost.atlassian.net/browse/MM-45956
