The quickest method for storing/loading MySQL data is using "SELECT INTO OUTFILE" and "LOAD DATA INFILE" statements. After an "LOAD DATA INFILE", indexes need to be rebuilded. In MEMORY (HEAP) data storage, indexes use hashed keys, but a computation of a hash value for records is slow. A solution to this issue is to store index structure into file when "SELECT INTO OUTFILE" is called and restore indexes when "LOAD DATA INFILE" is called. Program should be a patch against MySQL source, which: 1. On "SELECT INTO OUTFILE" will find all indexes of all MEMORY storage tables involved in query and saves them to separate or the same file. 2. On "LOAD DATA INFILE" will restore all indexes saved previously. You can assume that only one table will be involved in query and MEMORY storage with HASH keys (not BINARY) will be used for indexes.
