This release contains the implementation of HIP-873 adding token decimals to the REST API. Previously users had to make N + 1 queries to determine accurate token balance information by querying /api/v1/accounts/{id}/tokens once and /api/v1/tokens/{id} N times to get the relevant decimal information. This HIP adds decimals to both /api/v1/tokens/{tokenId}/balances and /api/v1/accounts/{id}/tokens so that decimal information is directly returned alongside the token relationships and the additional N queries are unnecessary. It also adds name and decimals fields to the /api/v1/tokens response to expose more of the existing token information on that API.
The /api/v1/contracts/call REST API now supports a configurable hedera.mirror.web3.evm.maxDataSize property so that mirror node operators can adjust how large of a payload they wish to support. The default value for the max data size was increased from 24 KiB to 25 KiB for creates and from 6 KiB to 25 KiB for calls. This change makes it possible for view functions with large inputs like oracles to now work on the network.
There were a few items to improve the performance and security of the mirror node. A new hedera.mirror.importer.downloader.maxSize=50MiB property controls the maximum stream file size it will attempt to download. This protects the mirror node against large files uploaded accidentally or via malicious actors. The importer was refactored to support batch stream file ingestion so that it is possible to process multiple stream files in one transaction. This will help pave the way for future enhancements like improving historical synchronization times.
The database saw a number of improvements including new setup documentation with recommendations for how to configure the database. Our Citus deployment had some notable additions including a huge improvement in performance by adjusting its resource configuration. The Stackgres version was upgraded to 1.8 and ZFS to 2.4.1. The entity stake calculation was optimized for Citus so it runs efficiently in a sharded database. Finally, database metrics were fixed so that partitioned tables are appropriately aggregated under the parent table name.
