Indexer GRPC file store

File store fetches data from cache and stores in Google Cloud Storage.

How to run it.

A service account json with write access to GCS.
- To bootstrap, please upload metadata.json to your bucket($FILE_STORE_BUCKET_NAME e.g., indexer-grpc-file-store):
json
```
  {
      "chain_id": 43,
      "blob_size": 1000,
      "version": 0
  }
```
- chain_id is the chain to process, immutable.
- blob_size is the number of transactions in each blob, immutable.
- version is the current version of transaction to process.
A Redis cache running at $REDIS_ADDRESS, e.g., 127.0.0.1:6379
Example command to run:

yaml

health_check_port: 8082
server_config:
    file_store_config:
      file_store_type: GcsFileStore
      gcs_file_store_bucket_name: indexer-grpc-file-store-bucketname
    redis_main_instance_address: 127.0.0.1:6379

Your bucket looks like:

bash

indexer-grpc-file-store-testnet/
    files/
        0.json
        1000.json
        ...
    metadata.json

[TEST ONLY] Run it with a local filestore

For developing and testing locally, it might be easier to use a local filestore.

Create a local directory to store the filestore: mkdir test_indexer_grpc_filestore

Then in your config:

yaml

...
server_config:
    file_store_config:
      file_store_type: LocalFileStore
      local_file_store_path: test_indexer_grpc_filestore
