Subject [jira] [Commented] (SOLR-11960) Add collection level properties
Date Wed, 21 Feb 2018 00:41:05 GMT


Tomás Fernández Löbbe commented on SOLR-11960:

Thanks [~prusko], patch looks great. I modified {{CollectionPropsTest.testReadWrite}} to check
immediately, since we are getting the value directly from ZooKeeper the change should be immediate,
there is no need to wait. I also added a test, {{CollectionPropsTest.testReadWriteCached}}
that adds a watcher, so that we do read the cached state. For that case we do need to wait
until the value is asynchronously set.
I’m going to upload a patch with my latest changes and commit shortly. Can you update the
docs for this new command?

> Solr has cluster properties, but no easy and extendable way of defining properties that
affect a single collection. Collection properties could be stored in a single zookeeper node
per collection, making it possible to trigger zookeeper watchers for only those Solr nodes
that have cores of that collection.
