I am using mysql 5.6.24 with innodb engine and facing issue like Lock wait timeout exceeded; try restarting transaction. here is the scenario. I'm trying to load 4800000 records from source to target database.
i am getting issue exactly at 3600000 records, alternative solution i given to my database with command like : set innodb_lock_wait_timeout=100

previously the size = 50 now increased to 100 but i hope this solution is not accurate for long time usage, could you please provide best approach.
