MySQL server instance displays the wrong server version after connection is established.Please refer to pricing tiers for the storage size limits per pricing tier.Support for VNet service endpoints is only for General Purpose and Memory Optimized servers.Restoring a deleted server is not supported.When using the PITR feature, the new server is created with the same configurations as the server it is based on.

MYSQL CONNECTION LIMIT UPGRADE

Major version upgrade is supported for v5.6 to v5.7 upgrades only.

Decreasing server storage size is not supported.

Dynamic scaling to and from the Basic pricing tiers is currently not supported.

Additionally, if you are using MySQL client version >= 8.0 you need to include -–local-infile=1 parameter in your connection string.

LOAD DATA INFILE is supported, but the parameter must be specified and directed to a UNC path (Azure storage mounted through SMB).

BACKUP_ADMIN privilege: Granting BACKUP_ADMIN privilege is not supported for taking backups using any utility tools.

LOAD_FILE(file_name): Not supported in the service.

INTO OUTFILE: Not supported in the service. You can't make changes to the mysql system database.

System databases: The mysql system database is read-only and used to support various PaaS functionality.

If importing data using a backup, remove the CREATE DEFINER commands manually or by using the -skip-definer command when performing a mysqlpump.

DEFINER: Requires super privileges to create and is restricted.

SUPER privilege: Similarly, SUPER privilege is restricted.

Alternatively, you can use the administrator user (created during new server creation), allows you to perform most of DDL and DML statements. Some data manipulation commands aren't supported. The MySQL service doesn't allow direct access to the underlying file system. To maintain the service integrity and SLA at a product level, this service doesn't expose multiple roles. Many server parameters and settings can inadvertently degrade server performance or negate ACID properties of the MySQL server. On Azure Database for MySQL, the following storage engines are supported and unsupported: Supported

MYSQL CONNECTION LIMIT PASSWORD

Password plugins such as "validate_password" and "caching_sha2_password" aren't supported by the service.

MYSQL CONNECTION LIMIT HOW TO

Refer to the Azure portal or Azure CLI articles for how to call the stored procedure and set the global or session-level time zones. The time zone tables can be populated by calling the mysql.az_load_timezone stored procedure from a tool like the MySQL command line or MySQL Workbench.

Upon initial deployment, an Azure for MySQL server includes systems tables for time zone information, but these tables are not populated. Refer to server parameters for more information about these limits. max_connections, join_buffer_size, query_cache_size) is determined by the pricing tier and vCores of the server. The min and max value of some parameters (ex. There is only 1 'free pass', so don't load up MWB twice if all the 'users' are 'root', too.Ĭonfigure Workbench to log in as user 'root give everyone else a non-super login.If you are looking for min/max values for server parameters like max_connections and innodb_buffer_pool_size, this information has moved to the server parameters article.Īzure Database for MySQL supports tuning the values of server parameters. Actually, if max_connections is 100, and you connect as root, then you can see 101 connections in the extreme case. MySQL reserves 1 connection (of the max_connections) for 'root'. Your use of Workbench may qualify for "admin stuff", so you could be justified in connecting as 'root'. No "user" and no "application" should connect as the SUPER user (typically called 'root' or 'admin') except when doing admin stuff. Otherwise, there is no hope of tracking them. 30 users should be using more than a single login. "Applications" and "users" should each have their own login. "Reserving 1 for MWB" - Let me ramble on for a moment before addressing this. What they should do is have a single connection for all database activity in the program. Some novice programmers make a connection inside a subroutine and fail to disconnect. Max_user_connections limits the number of simultaneous connections from any one user.Ī single program, including a single instance of Workbench, should (normally) make only one connection. I've searched google for few days trying to find answers without any luck. Since mysql is saying that connection limit is 500, I thought there are other setting in PHP, apache or codeigniter that is limiting the requests to mysql, but I cannot find any. Max_connections limits the number of simultaneous connections. show status returns that maxconnections and maxuserconnections to be 500.
