Unable to use taskbot in update mode from Roxy controller that uses query-router

[rjrudin]

I am working on a Roxy app that uses the Roxy rewriter. Each rewrite rule uses either the query-router or update-router.

I'm trying to use taskbot (which is a very nice library, btw) in a Roxy controller that uses the query-router. I am invoking taskbot:list-segment-process - the one that takes 6 arguments (sequence, batch size, job label, function, map, options). I am passing in OPTIONS-UPDATE for options.

My function attempts to insert a document. MarkLogic complains because of an update happening from a query transaction.

My assumption was that since taskbot should be executing the function on the task server, the fact that it does an update shouldn't impact the read-only transaction.

Have you run into this before with Roxy, and/or have any idea what I'm doing wrong? I'm working around the issue now by doing an xdmp:eval on the function that invokes taskbot so that taskbot is invoked in a separate transaction.

OPTIONS-UPDATE uses transaction-mode update, but latest ML supports update-auto-commit. Options might also need to include isolation different-transaction, which is not added to the predefined options either..
