Hi there, just a short question: When I have an index with documnets and the \_ttl set, and ES has been shut down, and gets started again, the documents that have expired in the meantime gets purged. Where exactly in the source code happens this? I was searching for ages but all I could find was the IndicesTTLService.java file but that one does not seem to be the right place. I suppose it happens somewhere in the recovery process. I tried to figure out by setting log level to trace but that did not give me the right place either. As always, any help is appreciated.

Once a node starts, the IndicesTTLService is also started. The IndicesTTLService starts the PurgerThread thread that periodically deletes all expired document for all indices that have a ttl configured. The deleting is actually performed in the PurgerThread#purgeShards method. If you set the 'indices.ttl' to 'DEBUG' in the logging.yml, you should see the related log lines.
