Subject EXPLAIN for DML statements
Date Fri, 23 Dec 2016 00:09:01 GMT
Alex P., Sergi,

All we know that EXPLAIN is not supported for DML statements at the moment.
http://apacheignite.gridgain.org/docs/dml#section-explain-support-for-dml-statements <http://apacheignite.gridgain.org/docs/dml#section-explain-support-for-dml-statements>

However, I can’t get how I can get over this limitation for UPDATE and DELETE statements
following this recommendation 

"One possible approach is to execute EXPLAIN for the SELECT automatically generated (UPDATE,
DELETE) or used (INSERT, MERGE) by DML statements. This will give an insight on the indexes
that are used while a DML operation is executed.”

How can I get SELECT queries that are generated by these DML operations automatically?
