Changes in MySQL Connector/Node.js 8.0.27 (2021-10-19, General Availability)

• Pluggable Authentication

• Functionality Added or Changed

• Bugs Fixed

Pluggable Authentication

• Added support for the following commercial authentication plugins: authentication_kerberos_client, mysql_clear_password, authentication_ldap_sasl_client (SCRAM-SHA1, SCRAM-SHA256 and GSSAPI), and authentication_oci_client

  Support is implemented using the required node-mysql2 driver. (WL #14743, WL #14744, WL #14745, WL #14746, WL #14747)

Functionality Added or Changed

• Unified the error and warning handling infrastructure. (WL #14617)

Bugs Fixed

• An unexpected error occurred when closing a client instance without a pool. This fix makes Client.close() functionally equivalent to Session.close() for standalone connections. (Bug #33175234)

• Improved the connection pool mechanism, namely parallelism issues that stemmed from exceeding mysqlx_max_connections as the pool was not properly queuing the request to acquire further connections when they become available. (Bug #33175092, Bug #104374)
