Commit 179c8f9b48af9bf3c327226d0e1fdbe460c4a325 in lucene-solr's branch
refs/heads/master from [~shalinmangar]
[ https://git-wip-us.apache.org/repos/asf?p=lucene-solr.git;h=179c8f9 ]
SOLR-11990: Make it possible to co-locate replicas of multiple collections
together in a node.
A collection may be co-located with another collection during collection
creation time by specifying a
'withCollection' parameter. It can also be co-located afterwards by using the
modify collection API.
The co-location guarantee is enforced regardless of future cluster operations
whether they are invoked
manually via the Collection API or automatically by the Autoscaling framework.

SOLR-11990: Extract ConditionType to an interface VarType along with a
WithCollectionVarType implementation
commit 1de2a4f52a59afca28de75bfa5156a3d6567a4f5
Author: Shalin Shekhar Mangar <sha...@apache.org>
Date: Tue Jul 24 12:53:26 2018 +0530
SOLR-11990: Pass strict-ness parameter to the ConditionType so that
WITH_COLLECTION can choose not to project add replica in strict mode.
This ensures that add replica or move replica suggesters always choose
nodes that already have withCollection replicas first unless there are
violations in doing so. Only if the first pass fails to find a suitable
replica, do we go to the other nodes in the cluster. This also removes the need
for the majority of changes in AddReplicaSuggester and so they've been reverted.

> It is necessary to co-locate replicas of different collection together in a
> node when cross-collection joins are performed.
> while creating a collection specify the parameter
> {{withCollection=other-collection-name}} . This ensure that Solr always
> ensure that atleast one replica of {{other-collection}} is present with this
> collection replicas
> This requires changing create collection, create shard and add replica APIs
> as well because we want a replica of collection A to be created first before
> a replica of collection B is created so that join queries etc are always
> possible.
> Some caveats to this implementation:
> # The {{other-collection}} should only have a single shard named "shard1"
> # Any replica of {{other-collection}} created by this feature will be of NRT
> type
> Removing the above caveats can be a goal of other issues.
