For security reasons, the Query DB Node smart service has been updated. Customers running the LOAD DATA INFILE command against a MySQL instance (only applicable to Configured Data Sources; not applicable to the Appian Cloud database) from a Query DB Node in a Process Model must set the conf.data.load.infile.paths custom property as a comma-separated list of file paths to whitelist the required directories. If the property is not set, any Process Model using this command will pause by exception at runtime. This command is generally used to periodically load data from files into the database, and so we expect that most customers will not have to take the required action described here.

The Memory Circuit Breaker now automatically detects when an expression is using too much memory and stops the evaluation before it can cause site-wide performance problems. See the Memory Circuit Breaker page for more information on how to diagnose memory issues and design memory-efficient expressions.
