Open / Close Index APIedit

The open and close index APIs allow to close an index, and later on opening it. A closed index has almost no overhead on the cluster (except for maintaining its metadata), and is blocked for read/write operations. A closed index can be opened which will then go through the normal recovery process.

The REST endpoint is /{index}/_close and /{index}/_open. For example:

curl -XPOST 'localhost:9200/my_index/_close'

curl -XPOST 'localhost:9200/my_index/_open'
