Hi Michael,
Thanks for your response. I am writing a custom cohort class for some
validation purpose, which extends the DOMDataTreeCommitCohort of the
mdsal.dom.api package and overrides the canCommit(). canCommit() in my cohort
does some validations and just return a Future object indicating success or
failure. I am NOT actually timing out the Future . Sometimes my cohort class
takes more than 5 seconds to execute and the MDSAL commit times-out. I suspect
that some classes in MDSAL are probably timing out the commit, since it is
exceeding the default timeout value of 5 seconds. But in my application, I can
wait for more than 5 seconds possibly around 20 seconds for doing the
validation. For this I want to know the code of the MDSAL which I can tweak for
setting a higher timeout value and use that code locally in my application.

Hi,

AFAIK, the 5s timeout you're experience below from a commit to the datastore is
probably not coming from mdsal (controller) code itself, but from something
using it .. if I were you I would look more at the code doing the commit - it
receives a Future in return, and some code in your application is probably
timing out on that Future - could that be?hh
Tx,
M.
