I encountered a failure in the replication to a spider table that is not mentioned in the recommendations at https://mariadb.com/kb/en/library/spider-storage-engine-overview/#some-server-variables-to-set-when-using-spider.
From 'show slave status\G':
It did work again after:
Can these issues be retried within the spider engine instead of failing in the engine and retried in the replication? (or are they failing after multiple attempts in the engine and the replication just continues to retry until it succeeds?)
Also I would expect the default settings to handle this, rather than having to add configuration mentioned in the link above.
