Hedera Hashgraph

Release Note

The new /api/v1/contracts/call REST API as specified in HIP-584 is finally ready for initial production use. This release adds support for rate limiting the API with an initial value of 100 requests per second per instance. Tags were added to the gas per second metric to indicate if the request was a call, an estimate, or resulted in an error for increased observability. Various bug fixes were also addressed.
HIP-668 GraphQL API was added to our deployment with the addition of a new helm chart for this API. This will allow for initial use of the API in all environments with the understanding that it's still very much alpha and subject to change.
We made a lot of headway on our Citus integration. Citus was upgraded to 11.2 which showed a nice 15-20% performance boost for a number of query patterns. We optimized the contract results APIs performance by distributing based upon contract ID instead of payer account. Search for a transaction by its hash on Citus was improved by adding the distribution column to the query and limiting the results to a timestamp range. The search for an account by its ID also saw improvements on Citus.
