Updates/Inserts frozen while index is being created on a DIFFERENT database
I ran into a issue that I just cant figure out. I am leveraging 5.7.31-34-57-log Percona XtraDB Cluster but this does not appear to be cluster related
Basically I have a quiet database table that has several million rows in it. I create a partial index on a text field (first 100 char) While this index creation is in progress updates and inserts on a totally different database are paused until the index creation is completed.
The reason I do not think that this is cluster related is I took the cluster down to a single node and was able to duplicate the issue
Why would a index creation on a table that very few people leverage impact updates on a table with no fk,triggers or events associated with the index creation
