Zili Chen resolved CURATOR-690. ------------------------------- Resolution: Fixed master via 51483adb1d1dd3e43812b5d0ec7c03b6d1d05c7c > CuratorCache fails to load the cache if there are more than 64K child ZNodes > ---------------------------------------------------------------------------- > > Key: CURATOR-690 > URL: https://issues.apache.org/jira/browse/CURATOR-690 > Project: Apache Curator > Issue Type: Improvement > Components: Recipes > Affects Versions: 5.5.0 > Reporter: Ryan Ruel > Assignee: Zili Chen > Priority: Major > Fix For: 5.6.0 > > > If there are more than 64K nodes in a tree which CuratorCache is watching, > the following exception is thrown: > {code:java} > java.lang.IllegalStateException: Attempt to register more than 65535 parties > for > org.apache.curator.framework.recipes.cache.CuratorCacheImpl$1@52354867[phase > = 0 parties = 65535 arrived = 0]{code} > As shown in the exception, this is due to the fact that > java.util.concurrent.Phaser hard-limits the maximum number of Phaser > registrants to 0xfff (64K). > A note in the Phaser documentation indicates why this limit exist and > proposes a solution using Tiered Phasers: > "Implementation notes: This implementation restricts the maximum number of > parties to 65535. Attempts to register additional parties result in > IllegalStateException. However, you can and should create tiered phasers to > accommodate arbitrarily large sets of participants." -- This message was sent by Atlassian Jira (v8.20.10#820010)
