From 5d3b1c0de5d112a5ae05ac9335224a469b6bfd17 Mon Sep 17 00:00:00 2001 From: Tigran Mkrtchyan Date: Tue, 4 May 2021 20:15:53 +0200 Subject: [PATCH] dcache-chimera: use RemotePoolMonitor to discover file locality Motivation: The DCacheAwareJdbcFs exposes file locality and uses in instance of RemotePoolMonitor for that. Unfortunately, a new instance is requested for each requests, which is more expensive, than directly querying the PoolManager. Modification: Update DCacheAwareJdbcFs to a single instance of RemotePoolMonitor. Update nfs door to subscribe to pool-monitor topic. Result: A single instance of RemotePoolMonitor is shared among multiple getlocality requests over nfs.
