-----------------------------------------

             Summary: Upgrade to Elasticsearch 7.0.0
                 Key: CALCITE-3023
                 URL: https://issues.apache.org/jira/browse/CALCITE-3023
             Project: Calcite
          Issue Type: Improvement
          Components: elasticsearch-adapter
            Reporter: Takako Shimamoto


Types are deprecated in APIs in 7.0, with breaking changes to the index creation, put mapping, get mapping, put template, get template and get field mappings APIs.
https://www.elastic.co/guide/en/elasticsearch/reference/7.0/removal-of-types.html

In this ticket, I propose that the name of the tables corresponds to indices in Elasticsearch.

For example:

*model.json*
{code:json}
{
  "version": "1.0",
  "defaultSchema": "elasticsearch",
  "schemas": [
    {
      "type": "custom",
      "name": "elasticsearch",
      "factory": "org.apache.calcite.adapter.elasticsearch.ElasticsearchSchemaFactory",
      "operand": {
        "coordinates": "{'127.0.0.1': 9200}"
      }
    }
  ]
}
{code}

*indices in Elasticsearch*
{code:bash}
root@50153d5029b6:/calcite# curl localhost:9200
{
  "name" : "50153d5029b6",
  "cluster_name" : "predictionio",
  "cluster_uuid" : "7drQAZjASgO5SFuuS7zXBA",
  "version" : {
    "number" : "7.0.0",
    "build_flavor" : "default",
    "build_type" : "tar",
    "build_hash" : "b7e28a7",
    "build_date" : "2019-04-05T22:55:32.697037Z",
    "build_snapshot" : false,
    "lucene_version" : "8.0.0",
    "minimum_wire_compatibility_version" : "6.7.0",
    "minimum_index_compatibility_version" : "6.0.0-beta1"
  },
  "tagline" : "You Know, for Search"
}
root@50153d5029b6:/calcite# curl -XGET 'http://localhost:9200/_cat/indices?v'
health status index   uuid                   pri rep docs.count docs.deleted store.size pri.store.size
yellow open   usa     tHUdsJZLRRS57knDyfD4Bg   1   1          2            0     10.1kb         10.1kb

{code}

We hope it displays like this:

{code:bash}
root@50153d5029b6:/calcite# ./sqlline 
sqlline version 1.7.0
sqlline> !connect jdbc:calcite:model=model.json admin admin
