### General configuration for NEAR ReadRPC
[general]
## Chain ID: testnet or mainnet
chain_id = "${CHAIN_ID}"

## Near network rpc url
## Using for proxying some requests to near network and to handle finality block
near_rpc_url = "${NEAR_RPC_URL}"

## near network archival rpc url
## Using for proxying some requests to near network and to handle historical data like proofs
## default value is None
near_archival_rpc_url = "${ARCHIVAL_NEAR_RPC_URL}"

## Referer header value
## We want to set a custom referer to let NEAR JSON RPC nodes know that we are a read-rpc instance
## Default value is "http://read-rpc.local"
referer_header_value = "${REFERER_HEADER_VALUE}"

## redis url using for pub/sub optimistic_block and final_block
## from near_state_indexer to rpc_server
## Default value is redis://127.0.0.1/
redis_url = "${REDIS_URL}"

### Rpc server general configuration
[general.rpc_server]

## Port for RPC server
## Default port is 8000
server_port = "${SERVER_PORT}"

## Max gas burnt for contract function call
## We allow to use max gas bunt to run contract function call
## Default value is 300_000_000_000_000
max_gas_burnt = "${MAX_GAS_BURNT}"

## Contract code cache in gigabytes
## By default we use 0.25 gigabyte (256MB or 268_435_456 bytes)
contract_code_cache_size = "${CONTRACT_CODE_CACHE_SIZE}"

## Block cache size in gigabytes
## By default we use 0.125 gigabyte (128MB or 134_217_728 bytes)
## One cache_block size is ≈ 96 bytes
## In 128MB we can put 1_398_101 cache_blocks
block_cache_size = "${BLOCK_CACHE_SIZE}"

## How many requests we should check for data consistency
## By default we use 100% of requests
## If you want to check 1% of requests, you should set 1
## thet means for every method calls will be checked every 100th request
shadow_data_consistency_rate = "${SHADOW_DATA_CONSISTENCY_RATE}"

## Max size (in bytes) for state prefetch during a view_call
## Limits the amount of data prefetched to speed up the view_call
## By default, it is set to 100KB (100_000 bytes).
prefetch_state_size_limit = "${PREFETCH_STATE_SIZE_LIMIT}"

### Tx indexer general configuration
[general.tx_indexer]

## Indexer ID to handle meta data about the instance
## Unique indexer ID
## Default value is "tx-indexer"
## If you run multiple instances of the indexer, you should change this value for each instance
indexer_id = "${TX_INDEXER_ID}"

## Port for metrics server
## By default it 8080 for tx-indexer and 8081 for state-indexer
metrics_server_port = "${TX_SERVER_PORT}"

### State indexer general configuration
[general.state_indexer]

## Indexer ID to handle meta data about the instance
## Unique indexer ID
## Default value is "state-indexer"
## If you run multiple instances of the indexer, you should change this value for each instance
indexer_id = "${STATE_INDEXER_ID}"

## Port for metrics server
## By default it 8080 for tx-indexer and 8081 for state-indexer
metrics_server_port = "${STATE_SERVER_PORT}"

## Concurrency for state-indexer
## Default value is 1
concurrency = "${CONCURRENCY}"

### Near state indexer general configuration
[general.near_state_indexer]

## Port for metrics server
## By default it 8082
metrics_server_port = "${NEAR_STATE_SERVER_PORT}"

## Concurrency for state-indexer
## Default value is 1
concurrency = "${NEAR_STATE_CONCURRENCY}"

### Tracking acconunts and state changes configuration
[rightsizing]

## Accounts to track. By default we track all accounts.
## You can specify a list of accounts to track.
## tracked_accounts = ["test.near"]
## By default we track all accounts.
tracked_accounts = "${TRACKED_ACCOUNTS}"

## State changes to track. By default we track all state changes.
## You can specify a list of state changes to track.
## Possible values: "state", "access_key", "contract_code"
## "accounts" are tracked from the `tracked_accounts` section
## tracked_changes = ["state", "access_key", "contract_code"]
## By default we track all state changes.
tracked_changes = "${TRACKED_CHANGES}"

### Lake framework configuration
[lake_config]

## Lake framework AWS access key id
aws_access_key_id = "${AWS_ACCESS_KEY_ID}"

## Lake framework AWS secret access key
aws_secret_access_key = "${AWS_SECRET_ACCESS_KEY}"

## Lake framework AWS default region
aws_default_region = "${AWS_DEFAULT_REGION}"

## Lake framework bucket name
aws_bucket_name = "${AWS_BUCKET_NAME}"

## Transaction details are stored in the Google Cloud Storage
[tx_details_storage]

## Storage Bucket Name
bucket_name = "${TX_BUCKET_NAME}"

## Database configuration
[database]

## Database connection string
## You can use database connection URL
## postgresql://{user}:{password}@localhost:5432/{db_name}
database_url = "${META_DATABASE_URL}"

## Database max connections
## Default value is 10
##The maximum number of connections that this pool should maintain.
## Be mindful of the connection limits for your database as well
## as other applications which may want to connect to the same database
## (or even multiple instances of the same application in high-availability deployments).

## A production application will want to set a higher limit than this.
## Start with connections based on 4x the number of CPU cores.
## For example, a 4-core machine might start with 16 connections.

## This parameter not needed to encrise for indexers
## 10 connections is enough for indexers to save changes to the database
max_connections = "${MAX_CONNECTIONS}"

## Database shards
## You can use multiple database shards
## Each shard should have a unique shard_id
## You can use the same database_url for all shards
## or use different database_url for each shard
## If you use different database_url for each shard, you should create a separate database for each shard
[[database.shards]]
