Added the following entry to the Connector/J 5.1.37 changelog:

"The code for executing a REPLACE statement when
rewriteBatchedStatements=true has been refactored by putting multiple
batched statements into a single query, making it work more like an
INSERT statement. This increases the efficiency for running REPLACE
statements. Thanks to Jie Han for contributing the patch."

we have billions records transfer from offline to online ,  rewrite
replace statement will save lots of bytes. and rewirte to one sql means
don't need  explicitly begin transaction ,because one sql will execute
in  a standalone transaction when autocommit is true,this save two
request for every batch. where network is slow autocommit will save more
time. hope rewrite replace statement will release in next version.
