Connector/j driver name
Client authentication plugins are now defined as services. This permits to easily add new client authentication plugins. New authentication plugins can be created implementing interface org. AuthenticationPlugin file. Custom SSL implementation can be used implementing A connection to a server initially creates a socket. When set, SSL socket is layered over this existing socket. Implementing org. Custom implementation need to implement org.
When any connection exception occurs, the stacktrace will a lot more verbose, containing the last 16 truncated exchanges with the server. The driver relies on the Slf4j framework. Slf4j is an abstraction for logging, which permits using the logger implementation of your choice. Configurations are implementation dependant, but, most of them need to indicate the package name that have to be logged, and log level.
Driver package is "org. Be careful with "trace" level, purpose is to log all exchanges with server. This means huge amount of data. Bad configuration can lead to problems, like quickly filling the disk. Example of configuring "trace" level on driver for logback: file logback. The last step is to indicate driver to generate logging, setting options "profileSql" or "log" to true. The source code is available at the mariadb-connector-j repository on GitHub.
Most of the time this will be caused by reading a query that has a large resultset; the server usually expects clients to read off the result set relatively quickly. If the client doesn't read the whole resultset in that amount of time, the server will discard the connection. If you don't expect results to be handled in this amount of time there is another possibility:. Knowledge Base Contact Login Search. Date Release Status Min.
Java Compat. Release Notes Changelog 16 Sep 3. This mode does not support load-balancing reads on slaves. The connector will try to connect to hosts in the order in which they were declared in the connection URL, so the first available host is used for all queries. If that host is not available, then it will try host2. When a host fails, the connector will try to reconnect to hosts in the same order. The connector performs load-balancing for all queries by randomly picking a host from the connection URL for each connection, so queries will be load-balanced as a result of the connections getting randomly distributed across all hosts.
Before 2. The mode supports environments with one or more masters. This mode does support load-balancing reads on slaves if the connection is set to read-only before executing the read. The connector performs load-balancing by randomly picking a slave from the connection URL to execute read queries for a connection. This mode does support load-balancing reads on slave instances if the connection is set to read-only before executing the read. The connector performs load-balancing by randomly picking a slave instance to execute read queries for a connection.
Parameter Description user Database user name. Default: 30 The applications that repeatedly use the same queries have value to activate this option, but the general case is to use the direct command text protocol. If set to false , queries are sent one by one, waiting for the result before sending the next one.
Results will be read later, avoiding a lot of network latency when the client and server aren't on the same host. This option is mainly effective when the client is distant from the server. More information here Default: true false if using aurora failover. Default: false. Since 2. The server will be added to trustStor. This permits a self-signed certificate to be trusted. When set, overrides serverSslCert. This option permits deactivating this validation.
Hostname verification is disabled when the trustServerCertificate option is set Default: false. Parameter Description pool Use pool. This option is useful only if not using a DataSource object, but only a connection object.
Default: 8. Should be less or equal to maxPoolSize. Default: maxPoolSize value. Default: in milliseconds. Must not be used with the useServerPrepStmts option Default: false. Default: true. Parameter Description log Enable log information. Log level correspond to Slf4j logging implementation Default: false.
Parameter Description passwordCharacterEncoding Indicate password encoding charset. Charset value must be a Java charset. May confuse 3rd party components Hibernated.
This permits better performance when the database is not in the same location. Using tcpAbortiveClose works around this problem by resetting TCP connections abortive or hard close rather than doing an orderly close.
It is accomplished by using socket. The value is the path of Unix domain socket i. The value is the base name of the shared memory. Value of 0 disables this timeout.
The advantage is that the connection then is still usable. Default: 0 standard configuration or ms using "aurora" failover configuration. Next use of that command, only prepared identifier and parameters if any will be sent to server.
This mainly permit for server to avoid reparsing query. Default: When option is active those queries are send using pipeline all queries are send, then only all results are reads , permitting faster connection creation. Hexadecimal value of those packets will be added to stacktrace when an IOException occur. This option has no impact on performance but driver will then take 16kb more memory. Default: empty. Default: 0. TlsSocketPlugin plugin type to use.
Plugin must be present in classpath Since 2. Parameter Description autoReconnect If this parameter is enabled and Failover and Load Balancing Mode is not in use, the connector will simply try to reconnect to its host after a failure. This is referred to as Basic Failover. If this parameter is enabled and Failover and Load Balancing Mode is in use, the connector will blacklist the failed host and try to connect to a different host of the same type.
This is referred to as Standard Failover. Default is false. Default: seconds. This parameter differs from the "retriesAllDown" parameter because this silent search is used in situations where the connector can temporarily workaround the problem, such as by using the master connection to execute reads when the slave connection fails. When this parameter is set to 0, no verification will be done.
Default seconds since 1. When connecting to a host, the driver will try to connect to a host in the list of non-blacklisted hosts and, only if none are found, attempt blacklisted ones. This blacklist is shared inside the classloader. Default: 50 seconds. Default to false. If no masters are available, then the default connection will be a slave, and Connection.
