Not blocking REA because of slow removal at a site

[chaen]

Problem seen by Juno and LHCb. Current solution is to distribute requests over time directly in the DB:

 update Request set NotBefore =  DATE_ADD(NOW(), INTERVAL FLOOR(RAND() * 3 * 24 * 60 * 60) SECOND)  where Status = 'Waiting' AND 
RequestName like '00293211_%';

Possible solution in the future:

• multiple dedicated REA
• TS submit requests already delayed requests

What is the problem you are seeing?

If removing a file at a site is very slow and you have a removal transformation hammering this site, you end up having all your REA threads busy on these slow removals, and no other requests move
