The main changes in this version are following.
Spider
- Add table parameter "active_link_count", "read_only_mode", "first_read" and "second_read".
- Add server parameter "spider_read_only_mode", "spider_first_read", "spider_second_read", "spider_remote_time_zone" and "spider_sync_time_zone".
"active_link_count" is a parameter for using Active-Standby database for data node. Normally, set "active_link_count" to 1 for using Active-Standby data node. Currently, this feature supports only Active-Standby that can switch immediately. For this changing, Spider's management table was changed from previous version, please execute "install_spider.sql" for upgrading.
- Reducing access to data nodes.
By this change, even if a shard is crushed, you can continue accessing to other shard.
Vertical Partitioning
This release is bug fix release.
Please see "99_change_logs.txt" in the download documents for checking other changes.
Enjoy!
