API specification

API Objective: Manage data sets.

The Collections API manages Fusion collections. It provides endpoints for creating, updating, and deleting collection, as well as endpoints for getting a collection’s status and usage statistics.

Fusion maintains internal system collections for logs, blobs, and metrics data which operate in conjunction with collections created by users. The Collections API is used to manage all Fusion collections.

Examples

In order to see this object within the Fusion UI, it must be associated with an app. To do this, create the object using the /apps endpoint.

Create a new collection called 'newCollection', with appropriate SolrCloud environment settings:

REQUEST

curl -u USERNAME:PASSWORD -X POST -H 'Content-type: application/json' -d '{"solrParams":{"replicationFactor":1,"numShards":1}}' https://FUSION_HOST:FUSION_PORT/api/collections/newCollection

RESPONSE

{
  "id" : "newCollection",
  "createdAt" : "2014-09-19T18:46:52.954Z",
  "searchClusterId" : "default",
  "solrParams" : {
    "name" : "newCollection",
    "numShards" : 1,
    "replicationFactor" : 1
  },
  "type" : "DATA",
  "metadata" : { }
}

Create a collection named 'local-collection1' that refers to 'collection1' in a pre-existing SolrCloud cluster named 'Solr4.10':

REQUEST

curl -u USERNAME:PASSWORD -X POST -H 'Content-type: application/json' -d '{"id":"local-collection1", "searchClusterId":"Solr4.10", "solrParams":{"name":"collection1"}}' https://FUSION_HOST:FUSION_PORT/api/collections

RESPONSE

{
  "id" : "local-collection1",
  "createdAt" : "2014-09-19T18:48:45.396Z",
  "searchClusterId" : "Solr4.10",
  "solrParams" : {
    "name" : "collection1"
  },
  "type" : "DATA",
  "metadata" : { }
}

Delete a collection, but keep the associated signals and searchLogs collections:

REQUEST

curl -u USERNAME:PASSWORD -X DELETE https://FUSION_HOST:FUSION_PORT/api/collections/newCollection?purge=false

Get the status of the 'demo' collection:

REQUEST

curl -u USERNAME:PASSWORD https://FUSION_HOST:FUSION_PORT/api/collections/demo/status

RESPONSE

{
  "maxShardsPerNode" : 1,
  "replicationFactor" : 1,
  "shards" : {
    "shard1" : {
      "range" : "80000000-7fffffff",
      "state" : "active",
      "replicas" : {
        "core_node1" : {
          "state" : "active",
          "core" : "demo_shard1_replica1",
          "leader" : true,
          "base_url" : "https://FUSION_HOST:8983/solr",
          "node_name" : "FUSION_HOST:8983_solr"
        }
      }
    }
  }
}

Get stats for the 'demo' collection:

REQUEST

curl -u USERNAME:PASSWORD https://FUSION_HOST:FUSION_PORT/api/collections/demo/stats

RESPONSE

{
  "collectionId" : "demo",
  "documentCount" : 536,
  "requestCount" : 6,
  "qps" : 28.34716542561849,
  "sizeInBytes" : 7646045,
  "lastModified" : "2014-05-19T19:58:33.545Z"
}

Add the recommendations feature for the 'tempy' collection:

For more information on collection features and feature management, see Collection Features API

Use this structure to send the request:

https://FUSION_HOST:FUSION_PORT/api/collections/{collection}/features/{feature}

curl -u USERNAME:PASSWORD -X POST -H 'Content-type: application/json' -d @enable-recommendations.json https://FUSION_HOST:FUSION_PORT/api/apps/Recommender-App/collections/tempy/features/recommendations -v

Make sure to change the collection-id in the JSON and save as a file or send directly in the string.
