The cluster wide defaults structure has changed from {collectionDefaults: {nrtReplicas : 2}} to {defaults : {collection : {nrtReplicas : 2}}}. The old format continues to be supported and can be read from ZK as well as written using the V2 set-obj-property syntax but it is deprecated and will be removed in Solr 9. We recommend that users change their API calls to use the new format going forward.
This commit deprecates the min_rf parameter. Solr now always includes the achieved replication
factor in the update requests (as if min_rf was always specified). Also, reverts the changes
introduced in SOLR-8034, replicas that don't ack an update will have to recover to prevent
inconsistent shards.
* added "ignored_*" to the default configSet
* Updated Ref Guide info on Solr Cell to demonstrate usage without using the techproducts configSet
Closes#438
Now, assignment is done with the help of a builder class instead of calling a method with large number of arguments. The number of special cases that had to be handled have been cut down as well.
The API now supports 'nrtReplicas', 'tlogReplicas', 'pullReplicas' parameters as well 'createNodeSet' parameter. As part of this change, the CREATESHARD API now delegates placing replicas entirely to the ADDREPLICA command and uses the new parameters to add all the replicas in one API call.
When retrying internal update requests, backoff only once for the full batch of retries
instead of for every request.
Make backoff linear with the number of retries
Simplified test utility TrackingUpdateProcessorFactory.
Reverted some attempts the TRA used to make in avoiding overseer communication (too complicated).
Closes#433
Cluster properties restriction of known keys only is relaxed, and now unknown properties starting with "ext."
will be allowed. This allows custom to plugins set their own cluster properties.
This commit adds support for preferredOperation configuration for NodeLostTrigger. The ComputePlanAction now creates DeleteNodeSuggester for each lost node serially when preferredOperation=deletenode. A new section for node lost trigger with exampls is added to the ref guide.
This commit adds support for preferredOperation configuration parameter which defaults to movereplica. Changes ComputePlanAction to add all (collection,shard) pair as hints to AddReplicaSuggester when addreplica is selected as the preferred operation.
