Release 1.0.0

This is the first major release of Heroic! \o/

Changes going forward will continue to follow semantic versioning.

The upgrade path for previous users of Heroic is to deploy new ElasticSearch 7.5 clusters. 7.5 has an EOL date of 2021-06-02 which at that time going to 8.x will require Heroic to migrate away from the transport client to the high level rest one.

The major change from 5.x -> 7.x is indexes no longer support multiple types.

• suggest has two types, series and tags. This means there will be 2x the number of indexes.
• metadata has only one type, metadata. There will be the same number of indexes.

Remove deprecated configuration options:

• Completely remove the StandaloneClient as it was removed in 6.x+. TestContainers are now used for the integration tests.
• Completely remove the NodeClient since it's not recommended to use anyway.

Example configuration for a metadata/suggest backend. Note that seeds and clusterName are now nested under client and not connection.

metadata:
  backends:
  - type: elasticsearch
    backendType: kv
    connection:
      index:
        type: rotating
        pattern: docker-cluster-%s
      client:
        type: transport
        clusterName: docker-cluster
        seeds:
          - localhost
