On your dashboard’s embedding settings page organization owners can see the number of times each dashboard has been embedded. This number corresponds to the number of times a dashboard has been requested for embedding with a completely new JWT and represents the number of times the queries associated with a dashboard have been sent to your database. If this number seems high, you may want to look into caching to avoid unnecessary load on your database.
Queries relating to an embedded dashboard are only run when the iframe
src url is requested with a brand new JWT. The results are cached for all subsequent requests until the JWT expires allowing an opportunity to pre-populate a cache with common iframe
src urls by requesting them server side before end users ever request the urls. This will eliminate any loading time end users would have had to endure waiting for the queries to complete. This is not required however, and the mechanism you choose to build this cache is entirely up to you (e.g. lazy load, batch job, etc.).
