Secondary indexes and stats [NDB-7.4]
Hello,
Using MySQL "5.6.37-ndb-7.4.16-cluster-gpl-log" version, it appears that query execution plan is not using secondary indexes.
I can see that for all the secondary indexes created, cardinality is null (unlike innodb where i can see cardinality calculated just after index creation).
Is there an option to update stats automatically ?
Is there a restriction on secondary indexes with this NDB version ?
Thanks for your help.
