hashgraph/hedera-mirror-node v0.9.0 on GitHub

This release contains another new REST API for our consensus service. You can now retrieve all topic messages in a particular topic, with additional filtering by sequence number and consensus timestamp. Here's an example:

GET /api/v1/topic/7?sequencenumber=gt:2&timestamp=lte:1234567890.000000006&limit=2

{
  "messages": [
    {
      "consensus_timestamp": "1234567890.000000003",
      "topic_id": "0.0.7",
      "message": "bWVzc2FnZQ==",
      "running_hash": "cnVubmluZ19oYXNo",
      "sequence_number": 3
    },
    {
      "consensus_timestamp": "1234567890.000000004",
      "topic_id": "0.0.7",
      "message": "bWVzc2FnZQ==",
      "running_hash": "cnVubmluZ19oYXNo",
      "sequence_number": 4
    }
  ],
  "links": {
     "next": "/api/v1/topic/7?sequencenumber=gt:2&timestamp=lte:1234567890.000000006&timestamp=gt:1234567890.000000004&limit=2"
  }
}

The other big feature of this release is Kubernetes support. We've created a Helm chart that can be used to deploy a highly available Mirror Node with a single command. This feature is still under heavy development as we work towards converting our current deployments to this new approach.
