------------------------------------------
Summary: clean cloud collection terms
Key: SOLR-15759
URL: https://issues.apache.org/jira/browse/SOLR-15759
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Components: Server
Affects Versions: 8.8.2
Reporter: Constantin Mitocaru
On cloud platforms we're expanding and contracting solr nodes using ASGs.
When a new VM instance shows up a new replica is created. When scaled in we
detect that and we delete the replica from ZK.
The problem is that, a marker for any replica, even destroyed is still kept in
the ZK terms file associated to that collection.
It all works fine until the size of the file
{color:#FF0000}*/collections/collName/terms/shard1*{color} exceeds 1MB in size
(this fills up for us in about 1 year). Then everything blows away as new
replicas cannot be registered in ZK.
So the request is the when a replica is deleted to also delete the term
associated with it from the terms file.
