Description of problem: Increasing number of entitlements in a single pool in manifest causes import time of the manifest to grow very rapidly. I.e. for manifest with 15k subscriptions, it took several minutes, but for manifest with 30k subscriptions, it didnt finish within 45 minutes(sic!). Checking candlepin logs, the cause is: 2015-12-01 07:40:44,026 [req=6868c8d9-121c-496b-a603-41c4c8847ae5, org=customer] INFO org.candlepin.controller.CandlepinPoolManager - Revoked entitlement: 2c9281204f5ff656014ffcf7fbc46d38 takes more and more time each. Having just partial logs (all to be attached), it ended after 45 minutes of importing in revoking one entitlement in 2 seconds(!). Since the time of processing one entitlement grows substantially over time, it is assumed some Map/Hash-like structure used in candlepin is very inefficient on insert or update when growing over some limit. Note also a valid workaround is to split the entitlements into more pools. Version-Release number of selected component (if applicable): seen on 6.0.8, supposed to be elsewhere How reproducible: 100% (expected, just seen at customer) Steps to Reproduce: 1. Create a manifest with 2x15k entitlements (15k entitlements in 2 pools each). 2. Import the manifest to Satellite 3. Create a manifest with 30k entitlements in single pool 4. Try to import it to the Satellite (after increasing rest_client_timeout in /etc/foreman/plugins/katello.yaml) Actual results: 2. succeeds, 4. doesnt wthin 45 minutes Expected results: both to succeed within similar time Additional info:
This should be fixed in Sat 6.1.7
