We switched over our test boxes with plan do move prod next week for the
new InCommon MDQ service. Java heap size went from 4GB to 1GB or less all
the time and the IDP starts up faster.
In case you missed this announcement below.
On January 30th, 2020, the InCommon Federation Technical Advisory
the production release <http://doi.org/10.26869/TI.142.1> of the new
InCommon metadata distribution service, featuring per-entity metadata.
InCommon strongly recommends you switch your SAML software to use the
metadata query or “MDQ” features in our new metadata service.
The InCommon “main” metadata aggregate is now almost 70MB in size, and
requires several gigabytes of memory to parse. This results in enormous
memory footprints and lengthy start-up times for your SAML software. MDQ
prevents your software from using these resources by allowing it to only
fetch the metadata it needs, when it needs it. You can also read about the
improvements we made with this service in a recent blog post by me
Moving to MDQ will require you to update the configuration of your SAML
software to point to a new metadata location and to verify the metadata
using a new public key. The details of all of this are in our new metadata
distribution service documentation, available in our wiki
<https://spaces.at.internet2.edu/x/2wR0C>. Make sure you look at the
documentation for Production rather than the Technical Preview (the latter
is the new version of the old “preview” metadata aggregate service).
Over the next year, we will work with you to transition all InCommon
federation SAML software to the new service; changing to the new service
sooner rather than later is recommended.
