Indexer Integration

[l-monninger]

Summary

• RFCs: $\emptyset$
• Categories: protocol-units
• Associated PRS
  • Indexer Instrumentation aptos-indexer-processors#1
  • Adjustments to Indexer for Use of Indexer gRPC Service aptos-core#26

Adds support for serving Indexer gRPC stream from Suzuka Full Node.

Changelog

1. Bootstrapping for tasks needed to serve gRPC service added.
2. gRPC RawData indexer service added.
3. Indexer Processor instrumented and added as crate. However, this is somehow incompatible with the gRPC stream provided.

Testing

1.Standard e2e tests are still passing.
2. Health-check on gRPC service.

Outstanding issues

1. For whatever, even though they are using the same protos, the indexer-processor receives a gRPC Unimplemented error when trying to read the GetTransactions stream from the indexer gRPC service.
2. More robust testing should be added.
3. A GraphQL server will need to be implemented over the indexer-processor DB.

This is going to need to be heavily reworked, so I am going to close.
