When MRR is used, the Extra column in EXPLAIN output shows Using MRR. InnoDB and MyISAM do not use MRR if full table rows need not be accessed to produce the query result. This is the case if results can be produced entirely on the basis on information in the index tuples (through...
Inserting the record can include determining a first hash value from a first dimension value of the record and determining a first set of candidate partitions from the first hash value. The method can further include determining a second hash value from a second dimension value of the record ...
