AMP Memory Use

Last modified: June 03, 2020

Now that we know more about Alteryx Engine, AMP and the main differences between the two, let’s take a look at the memory usage and configuration.


The default memory usage for AMP is 25% of available machine memory. The minimum memory requirements include the following:

  • The AMP engine must have at least 400 MB per thread to run a workflow. 399 MB produces an error.
  • The original engine must have at least 64 MB to run a workflow. 63 MB produces an error.

Note that AMP carries the data more efficiently, so the data streams are smaller than with the original engine.

Sort/Join Memory

The Sort/Join Memory setting in Designer defines the maximum amount of memory that the engine might use to execute a workflow. Use the default setting for running a single workflow, and decrease the setting if you need to run multiple workflows at a time.

To edit the default Sort/Join Memory value, select the white space of the canvas, navigate to the Configuration pane, and select the Runtime tab.

Increasing the Sort/Join Memory limit value can improve the performance of the engine because more data can stay in memory instead of moving to temporary files. Increasing the Sort/Join Memory limit may decrease performance of processes beyond the engine.
