I'm pleased to announce the release of Spider storage engine version 0.13.(beta)
The main changes in this version are following.
- Add table parameter "crd_bg_mode" and "sts_bg_mode".
- Add server parameter "spider_crd_bg_mode" and "spider_sts_bg_mode".
MySQL needs table's analysis informations when select statement is executed. Spider storage engine gets this informations from remote table but this action often generates over-heads.
This options remove generated over-heads by getting analysis informations at background but you must set this option to 0 if the table's analysis informations change frequently.
* There are other options for the over-heads reduction of the analysis informations acquisition. I will introduce this at another time.
Please see "99_change_logs.txt" in the download documents for checking other changes.
