throtcat is a cat(1) -style program that throttles it throughput based
on external criteria.
Two criteria for throttling are available:
time: pause N milliseconds between each input lineinnodb: connect to a MySQL server, observe its InnoDB engine metrics and pause when certain thresholds are reached
It can be used in a scenario such as
$ throtcat [OPTIONS] < big_dump.sql | mysql -hmysql.foo.com -u... -p... DBNAME
to import a large database to mysql.foo.com while trying not to overload it.
TBD
The program simply tokenises its input by newlines. You may want to instruct
your mysqldump(1) to output SQL statements line-by-line, although that
shouldn't be strictly necessary.
