Index Management Plugin

You can use the Index Management Plugin (ISM) API to programmatically automate periodic, administrative operations on indexes by triggering them based on changes in the index age, index size, or number of documents.

Create a Policy

policy_name = "test-policy"

policy_content = {
    "policy": {
        "description": "hot warm delete workflow",
        "default_state": "hot",
        "schema_version": 1,
        "states": [
            {
                "name": "hot",
                "actions": [{"rollover": {"min_index_age": "1d"}}],
                "transitions": [{"state_name": "warm"}],
            },
            {
                "name": "warm",
                "actions": [{"replica_count": {"number_of_replicas": 5}}],
                "transitions": [{"state_name": "delete", "conditions": {"min_index_age": "30d"}}],
            },
            {

                    },
                    {"delete": {}},
                ],
