v0.3.1

Supported Nearcore Version

• nearcore v2.3.0
• rust v1.81.0

What's Changed

• Improved bulk insertion of state_changes, reducing database requests from hundreds to a maximum of 7 per block.
• Configuration improvement. Create default config.toml on start application to loaded parameters from the environment variables.
• Fix to fetch state by pages (view_state_paginated).
• Change logic to get shard_layout for indexers. Main idea to avoid request protocol_config via RPC, protocol_config could be changed with new nearcore release and we should support old and new versions of protocol_config.

0.3.0

BREAKING CHANGES

Please, see the PostgreSQL & ShardLayout Pull Request for details. This is a completely new version of the ReadRPC with a new data storage layout and a new data storage engine. The main changes are:

• Migrate from ScyllaDB to PostgreSQL for storing the data. We adopted the ShardLayout from the nearcore and split the data to separate PostgreSQL databases for each shard.
• Changed the way we store TransactionDetails (JSON blobs again, but it might change soon)

All the work in this release allowed us to increase the performance of the ReadRPC and make it more reliable. We are still working on the performance improvements and will continue to work on the ReadRPC to make it even better.
