问题 does anyone know where I can found the highest value of max_connections in AWS RDS? I'm primarily interested in the db.t2 instances running MySQL. I cannot find any appropriate link about that.

On RDS can I create Tables in a Read Replica that are not present on the Master?

由 我的梦境 提交于 2019-12-22 04:11:10
问题 We have a separate RDS Instance to handle session state tables, however found that the session DB load is very low. if we can convert the instance handling session as a Read Replica of the main DB, then we can use it for read-only tasks that are safe even with a large lag in the copy. Has anyone done something like this on RDS (Is it possible and safe)? Should I watch out for any serious side effects? Any links or help in understanding this better would help. http://aws.amazon.com/rds/faqs/

.NET CORE MySql MaxPoolSize not applied in

由 耗尽温柔 提交于 2019-12-22 00:45:06

I've verified this in MySqlWorkbench with the command

由 南楼画角 提交于 2019-12-21 18:03:18
问题 MySQL allows parameter SQL_MODE to be set to multiple values in the my.cnf file. How can I do the same on Amazon RDS? UPDATE: This problem has been fixed...see below. 回答1: Helpfully it looks like Amazon have fixed this as of May 24th 2016 "The sql_mode parameter can now be set to a list of values for all MySQL and MariaDB versions. The list of values should be correct in all regions as well." https://forums.aws.amazon.com/thread.jspa?threadID=232266 回答2: MySQL allows parameter SQL_MODE to be

ERROR 1465 “Triggers can not be created on system tables” after restore from SQL created by mysqldump

问题 I'm running a mysql 5.6 server on amazon RDS and set up a read replica I use to create backups using mysqldump. I tried with the "--all-databases" option, but when I'm trying to import the SQL created by mysqldump, I end up with this error from the mysql command client: ERROR 1465 "Triggers can not be created on system tables" I used "--all-databases" because I basically want to restore everything in RDS as it was before in case of a crash. Maybe that's wrong, and I should only select my
