Jira issue: https://jira.percona.com/browse/FB8-52 Reference Patch: facebook@80ca845 Reference Patch: facebook@0fb428b ---------- facebook@80ca845 ---------- Summary: This diff added a configurable variable to throttle the write rate of new innodb log file initialization. Default speed is 128MB/second, and setting it to 0 will turn off the throttling. I also changed the default value of innodb_fsync_freq to 1MB to reduce system stalls caused by fsyncing large trunks of file. Test Plan: jenkins Testing command: mysqld --datadir=/tmp/log_init --skip-grant-tables --skip-networking --socket=socket --innodb-log-file-size=1G --innodb-txlog-init-rate=[rate] With --innodb-txlog-init-rate=0 (no throttling, 1GB init finished in ~49s) 2015-05-22 16:51:20 4018018 [Note] InnoDB: Setting log file ./ib_logfile101 size to 1024 MB InnoDB: Progress in MB: 100 200 300 400 500 600 700 800 900 1000 2015-05-22 16:52:09 4018018 [Note] InnoDB: Setting log file ./ib_logfile1 size to 1024 MB InnoDB: Progress in MB: 100 200 300 400 500 600 700 800 900 1000 With --innodb-txlog-init-rate=10485760 (10MB/s throttling, 1GB log init finished in ~103s) 2015-05-22 16:55:28 4022136 [Note] InnoDB: Setting log file ./ib_logfile101 size to 1024 MB InnoDB: log file write is throttled at 10MB/s InnoDB: Progress in MB: 100 200 300 400 500 600 700 800 900 1000 2015-05-22 16:57:11 4022136 [Note] InnoDB: Setting log file ./ib_logfile1 size to 1024 MB InnoDB: log file write is throttled at 10MB/s InnoDB: Progress in MB: 100 200 300 400 500 600 700 800 900 1000 Without setting the option (use default. 1GB init finished in ~50s.

We could get the throttle rate from the global variable innodb_txlog_init_rate anyway. Test Plan: jenkins Originally Reviewed By: santoshb

Reference Patch: 80ca845
Reference Patch: 0fb428b
Patch introduces new variable 'innodb_txlog_init_rate' to limit
the IO rate of InnoDB redo log file initialization.
Test Plan:
jenkins
Testing command:
mysqld --datadir=/tmp/log_init --skip-grant-tables --skip-networking --socket=socket --innodb-log-file-size=1G --innodb-txlog-init-rate=[rate]
With --innodb-txlog-init-rate=0 (no throttling, 1GB init finished in ~49s)
2015-05-22 16:51:20 4018018 [Note] InnoDB: Setting log file ./ib_logfile101 size to 1024 MB
InnoDB: Progress in MB: 100 200 300 400 500 600 700 800 900 1000

With --innodb-txlog-init-rate=10485760 (10MB/s throttling, 1GB log init finished in ~103s)
2015-05-22 16:55:28 4022136 [Note] InnoDB: Setting log file ./ib_logfile101 size to 1024 MB
InnoDB: log file write is throttled at 10MB/s
InnoDB: Progress in MB: 100 200 300 400 500 600 700 800 900 1000

InnoDB: Progress in MB: 100 200 300 400 500 600 700 800 900 1000
Without setting the option (use default. 1GB init finished in ~50s. Note the write is already below 128MB/s, so the throttling didn't have any effect)
2015-05-22 17:18:51 4055898 [Note] InnoDB: Setting log file ./ib_logfile101 size to 1024 MB
