v0.34.0

[steven-sheehy]

In Hedera Mirror Node v0.34.0, we started work on designing support for NFTs that will come in a future Hedera Services release.

By default, the mirror node will validate that at least one-third of all nodes in the address book have signed a stream file before importing it into its database. This ensures that the main nodes have reached two-thirds consensus on the transactions in the file. For performance or verification reasons, you may want to decrease or increase this default percentage. To support this use case, we added a hedera.mirror.importer.downloader.consensusRatio property that controls the ratio of verified nodes (nodes used to come to consensus on the signature file hash) to the total number of nodes available.

We took the time to undertake some major dependency upgrades for the Rosetta API. This included major updates to the Hedera and Rosetta SDKs that both required a large amount of refactoring. A number of bugs in Rosetta were addressed as well as improvements to Rosetta's CI workflow. These changes lay the groundwork for additional Rosetta improvements in a future release.

To avoid duplication, we wanted to unify our JMeter and Monitor performance tests. To do so, we needed the newer monitor tool to have feature parity with our JMeter tests. To accomplish this, we've split the publish to HAPI and subscribe to mirror node flows in the monitor to allow for subscribe only. In this iteration only the gRPC API supports subscribe only. With this change, we were able to remove our JMeter code and optimize the hedera-mirror-test image from 1.5G to 0.5G.

We made some operational improvements to our helm chart including alert dependencies. Alert dependencies help avoid a flood of alerts that are all related to the same root cause. We also made some bug fixes to the chart that could occur when enabling or disabling some components in favor of external databases or message buses.
