admin:group-get-background-io-limit

admin:group-get-background-io-limit(
   $config as element(configuration),
   $group-id as xs:unsignedLong
) as xs:unsignedInt

Summary

This function gets the value for the I/O background limit that controls the I/O resources that I/O tasks (for example, merges) will consume. If the limit is reached, then merges are throttled back to limit their maximum I/O. This can help in situations when the I/O system on the computer is maxed out. In normal operations, you should not need to set this parameter.

  let $config := admin:get-configuration()
  let $groupid := admin:group-get-id($config, "Default")
  return
  admin:group-get-background-io-limit($config, $groupid)

  (: Returns the background I/O setting for the Default group. :)
