Workers

Workers can be individually configured using the worker configuration file, which allows for persistent modifications to be made. Persistent modification refers to changes made to a system or component that are saved and retained even after the system is restarted or shut down, allowing the modifications to persist over time.

It is worth noting that the worker configuration file is not subject to frequent changes on a daily basis, providing stability to the system’s configuration.

Flag Name	Who May Configure	Description	Data Type	Default Value
cudaMemQuota	SUPERUSER	Sets the percentage of total device memory used by your instance of SQream.	uint	90
healerMaxInactivityHours	SUPERUSER	Used for defining the threshold for creating a log recording a slow statement. The log includes information about the log memory, CPU and GPU.	bigint	5
isHealerOn	SUPERUSER	Enables the Query Healer, which periodically examines the progress of running statements and logs statements exceeding the healerMaxInactivityHours flag setting.	boolean	TRUE
limitQueryMemoryGB	Anyone	Prevents a query from processing more memory than the defined value.	uint	100000
loginMaxRetries	SUPERUSER	Sets the permitted log-in attempts.	bigint	5
machineIP	SUPERUSER	Enables you to manually set the reported IP.	string	127.0.0.1
maxConnections	SUPERUSER	Defines the maximum allowed connections per Worker.	bigint	1000
metadataServerPort	SUPERUSER	Sets the port used to connect to the metadata server. SQream recommends using port ranges above 1024 because ports below 1024 are usually reserved, although there are no strict limitations. You can use any positive number (1 - 65535) while setting this flag.	uint	3105
useConfigIP	SUPERUSER	Activates the machineIP (TRUE). Setting this flag to FALSE ignores the machineIP and automatically assigns a local network IP. This cannot be activated in a cloud scenario (on-premises only).	boolean	FALSE
