Problem statement

This article explains the meaning of the 32kb Action Limitation for user_metadata and app_metadata per session.

Solution

The app_metadata and user_metadata have a combined size limit of 16MB as noted in the document Size limits and Storage of Metadata Field Names and Data types.

  • It is only possible to save (persist) 32kB of data to each of the user_metadata and app_metadata per execution of an Action (as in, each metadata field can save 32kB each).
