• socksProxyHost

  Name or IP address of SOCKS host to connect through.

  Since Version	5.1.34

• socksProxyPort

  Port of SOCKS server.

  Default Value	1080
  Since Version	5.1.34

• socketFactory

  The name of the class that the driver should use for creating socket connections to the server. This class must implement the interface com.mysql.cj.protocol.SocketFactory and have public no-args constructor.

  Default Value	com.mysql.cj.protocol.StandardSocketFactory
  Since Version	3.0.3

• connectTimeout

  Timeout for socket connect (in milliseconds), with 0 being no timeout. Only works on JDK-1.4 or newer. Defaults to '0'.

  Default Value	0
  Since Version	3.0.1

• socketTimeout

  Timeout (in milliseconds) on network socket operations (0, the default means no timeout).

  Default Value	0
  Since Version	3.0.1

• dnsSrv

  Should the driver use the given host name to lookup for DNS SRV records and use the resulting list of hosts in a multi-host failover connection? Note that a single host name and no port must be provided when this option is enabled.

  Default Value	false
  Since Version	8.0.19

• localSocketAddress

  Hostname or IP address given to explicitly configure the interface that the driver will bind the client side of the TCP/IP connection to when connecting.

  Since Version	5.0.5

• maxAllowedPacket

  Maximum allowed packet size to send to server. If not set, the value of system variable 'max_allowed_packet' will be used to initialize this upon connecting. This value will not take effect if set larger than the value of 'max_allowed_packet'. Also, due to an internal dependency with the property "blobSendChunkSize", this setting has a minimum value of "8203" if "useServerPrepStmts" is set to "true".

  Default Value	65535
  Since Version	5.1.8

• socksProxyRemoteDns

  When using a SOCKS proxy, whether the DNS lookup for the database host should be performed locally or through the SOCKS proxy.

  Default Value	false
  Since Version	8.0.29

• tcpKeepAlive

  If connecting using TCP/IP, should the driver set SO_KEEPALIVE?

  Default Value	true
  Since Version	5.0.7

• tcpNoDelay

  If connecting using TCP/IP, should the driver set SO_TCP_NODELAY (disabling the Nagle Algorithm)?

  Default Value	true
  Since Version	5.0.7

• tcpRcvBuf

  If connecting using TCP/IP, should the driver set SO_RCV_BUF to the given value? The default value of '0', means use the platform default value for this property)

  Default Value	0
  Since Version	5.0.7

• tcpSndBuf

  If connecting using TCP/IP, should the driver set SO_SND_BUF to the given value? The default value of '0', means use the platform default value for this property)

  Default Value	0
  Since Version	5.0.7

• tcpTrafficClass

  If connecting using TCP/IP, should the driver set traffic class or type-of-service fields ?See the documentation for java.net.Socket.setTrafficClass() for more information.

  Default Value	0
  Since Version	5.0.7

• useCompression

  Use zlib compression when communicating with the server (true/false)?

  Default Value	false
  Since Version	3.0.17

• useUnbufferedInput

  Don't use BufferedInputStream for reading data from the server

  Default Value	true
