Note: Installing these packages requires Rust and it's package manager cargo to be installed so that the cost model module can be built. If you already have Rust installed, make sure you're on the latest stable release. Installing the above packages may also require passing --unsafe-perm=true to the above install commands.

Docker

docker pull ghcr.io/graphprotocol/indexer-agent:v0.18.6
docker pull ghcr.io/graphprotocol/indexer-service:v0.18.6

Changes (Overview)

The most notable change included in this release is the addition of support for type 02 transactions as specified in EIP-1559.
The agent will now send type 02 transactions if supported by the client. Parallel allocations are being deprecated and will
automatically be removed by the agent now if found, in future releases all vestiges of parallel allocation management
will be removed. Another valuable update to the indexer-agent bring significant gas efficiency gains by batching claim transactions.

The indexer-cli has received some subtle, but important, updates to the status command outputs. 2 tables have been added
to the status output showing the indexer's 1. active allocations and 2. subgraph deployments.

Configuration options updates with this release (all optional):

Removed

Environment Variable CLI Option
INDEXER_AGENT_ALLOCATION_CLAIM_THRESHOLD --allocation-claim-threshold

Added

Environment Variable CLI Option Recommended Value
INDEXER_AGENT_REBATE_CLAIM_THRESHOLD --rebate-claim-threshold 250
INDEXER_AGENT_REBATE_CLAIM_BATCH_THRESHOLD --rebate-claim-batch-threshold 1000

Changes (Per Component)

Indexer Agent

Added

  • Support type 0x2 transactions (EIP-1559)
  • Close all parallel allocations and only renew a single allocation per deployment
  • Include an additional state for indexing dispute monitoring, references_unavailable, for the case where the indexer does not have a reference PoI available. Typically this case occurs when an indexer's deployment is not synced far enough

Changed

  • Deprecate the parallel allocations feature
  • Update Ethers dependencies
  • Keep deployment indexing for 1 day after allocation close
  • Reducing transaction logging redundancy to improve readability
  • Bump priority gas fee on gas price too low retry
  • Simplify transaction retry logic on nonce collisions; agent now introduces a delay and returns to reconciliation step to re-evaluate

Fixed

  • Only add prefix to voucher address if not present
  • Bump type 2 transaction gas fee configs on retry after timeout
  • Update max-transaction-attempts default to unlimited to avoid orphaned transactions
  • Treat deployments assigned to node = null or undefined as removed, so they are filtered out of the activeDeployments array
  • Fix delete query fee vouchers logic, so they are actually removed after the expiration time
  • Update tests to use the latest version of the Indexer class constructor

Indexer Service

Added

  • Support unattestable query responses

Changed

  • Broaden scope of allocations eligible for receiving traffic to include those recently closed
  • Update Ethers dependencies

Fixed

  • Use ENTRYPOINT instead of CMD in dockerfile so users can specify command line arguments in docker run command

Indexer CLI

Added

  • Show the status of indexer's active allocations in status command output
  • Show the status of indexer's subgraph deployments in status command output

Changed

  • Update Ethers dependencies

Indexer Common

Changed

  • Update Ethers dependencies

Indexer Native

Fixed

  • Fix build for Node v16 by upgrading neon-sys dependency.

Docker

docker pull ghcr.io/graphprotocol/indexer-agent:v0.17.0
docker pull ghcr.io/graphprotocol/indexer-service:v0.17.0

Changes (Overview)

This release primarily contains updates to the indexer agent to improve efficiency. The process of reallocating towards a subgraph deployment has been updated to use closeAndAllocate(), so it requires one transaction instead of two (close then allocate). Handling of high gas price scenarios has also been improved; when estimated gas prices exceed the threshold the agent will now enter a holding pattern where it waits for gas prices to return to below the gas-price-max before continuing with transaction execution. Along with the updated behavior, the gas-price-max startup argument has been updated for ease of use to be denominated in gwei rather than wei.

There were a few additional minor improvements to indexer agent:

  • improved handling of empty auth fields for the Ethereum endpoint,
  • more clear log messages from subgraph query errors.

Some networking optimizations have been included for both the indexer service and indexer agent:

  • both recommended k8s setups have both been updated to use a ClusterIP service instead of LoadBalancer since the LoadBalancer services have been shown to introduce more latency and their extra features aren't required here,
  • /network execution has been optimized by switching to a simpler HTTP client (doesn't need to be GraphQL aware).

As promised in the last release, this release includes an update to make the /network endpoint optional and introduces a dedicated (optional) auth token for /network requests.

New configuration options with this release (all optional):

Environment Variable CLI Option Recommended Value
INDEXER_AGENT_NETWORK_SUBGRAPH_AUTH_TOKEN --network-subgraph-auth-token <Secret bearer token for network queries>
INDEXER_AGENT_SERVE_NETWORK_SUBGRAPH --serve-network-subgraph true
INDEXER_AGENT_VOUCHER_EXPIRATION --voucher-expiration 2160

Changes (Per Component)

Indexer Agent

Added

  • Reallocate to subgraph deployment in one transaction using closeAndAllocate.
  • Wait for gas prices below the gas-price-max (gwei) before proceeding with transaction execution.
  • Add --voucher-expiration to configure the time (in seconds) after which a voucher with too few query fees is permanently deleted. Until then, keep retrying to redeem it to give the indexer a chance to adjust their --allocation-claim-threshold.

Changed

  • Show subgraph query error reason in logs.
  • Use ClusterIP in the k8s indexer agent service rather than a LoadBalalancer since LoadBalancer services have been
    shown to introduce extra latency.
  • Use undefined for auth user and password if none specified.
  • Update gas-price-max units to be gwei instead of wei for improved human readability.
  • Default gas-price-max changed from 20 gwei to 50 gwei.

Fixed

  • Improve robustness of subgraph deployments query by querying batches of only 10 deployments at a time.

Indexer Service

Changed

  • Make the /network endpoint optional by default and introduce a dedicated (optional) auth token for /network requests.
  • Optimize /network execution by switching to a simpler HTTP client (doesn't need to be GraphQL aware).
  • Use ClusterIP in the k8s indexer service service rather than a LoadBalalancer since LoadBalancer services have been
    shown to introduce extra latency.

Indexer CLI

Fixed

  • Remove vestigial check for channel-messages-inbox endpoint.

Indexer Common

Changed

  • Optimize /network execution by switching to a simpler HTTP client (doesn't need to be GraphQL aware).

Indexer Native

Fixed

  • Fix build for Node v16 by upgrading neon-sys dependency.

Docker

docker pull ghcr.io/graphprotocol/indexer-agent:v0.16.0
docker pull ghcr.io/graphprotocol/indexer-service:v0.16.0

Changes (Overview)

This is a minor release that introduces smaller changes, mostly to improve indexer agent transactions:

  1. The revert reason of transactions is now detected to avoid retrying transactions that have no chance of succeeding.
  2. The default value for INDEXER_AGENT_TRANSACTION_ATTEMPTS / --transaction-attempts has been reduced from 5 to 2.
  3. The INDEXER_AGENT_ALLOCATION_CLAIM_THRESHOLD / --allocation-claim-threshold option has been extended to not only apply to claim transactions but also to redeeming query fee vouchers. This can help avoiding to collect query fees that are lower than the actual transaction cost.

Another change is that indexer service and indexer agent now both use the same network subgraph query logic, i.e. first trying a local deployment (if specified), otherwise falling back to querying the network subgraph via an (often external) endpoint. This means it is no longer necessary to point the indexer service at indexer agent. Instead, it is recommended to configure them both in the same way.

For mainnet, the recommended values are:

Environment Variable CLI Option Value
INDEXER_AGENT_NETWORK_SUBGRAPH_DEPLOYMENT --network-subgraph-deployment QmaUBw7sr8pBrwNgz6JkbmmGoUU7KJSaeRvCaY3NPDbQ7A
INDEXER_AGENT_NETWORK_SUBGRAPH_ENDPOINT --network-subgraph-endpoint https://gateway.thegraph.com/network
INDEXER_SERVICE_NETWORK_SUBGRAPH_DEPLOYMENT --network-subgraph-deployment QmaUBw7sr8pBrwNgz6JkbmmGoUU7KJSaeRvCaY3NPDbQ7A
INDEXER_SERVICE_NETWORK_SUBGRAPH_ENDPOINT --network-subgraph-endpoint https://gateway.thegraph.com/network

This release also introduces a /network route in the indexer service. This, by default, is protected via the INDEXER_SERVICE_FREE_QUERY_AUTH_TOKEN / --free-query-auth-token. It is safe, even advised, to keep this endpoint internal.

Addendum: It was planned to make the /network endpoint disabled by default. This will happen in a follow-up bugfix release.

Changes (Per Component)

Indexer Agent

Changed

  • Default to only one transaction retry attempt to reduce gas usage
  • Apply allocation claim threshold to redeeming query fee vouchers as well
  • Add the same network subgraph fallback logic as the agent uses

Fixed

  • Improve handling of reverted transactions by detecting the revert reason

Changes (Overview)

Launch of Scalar on Mainnet

The main change in this release is the replacement of State Channels with Scalar (using allocation-base receipts for now). Scalar enables highly scalable micro-transactions for query fees.

At a high level this means:

  • Along with every query, indexers now receive an updated Scalar receipt via the Scalar-Receipt header.
  • Receipts are collected via a /collect-receipts endpoint on the gateways. This will convert them into a signed (query fee) voucher that can then be redeemed via a new AllocationExchange contract on chain.

With this release, the indexer infrastructure changes as follows:

  • A new INDEXER_AGENT_COLLECT_RECEIPTS_ENDPOINT / --collect-receipts-endpoint configuration option is added to Indexer Agent to configure the endpoint that converts bundles of receipts into query fee vouchers.
  • A new INDEXER_SERVICE_CLIENT_SIGNER_ADDRESS / --client-signer-address configuration option is added to Indexer Service to configure the signer of the incoming receipts. For now, this limits indexers to being able to serve a single client, which is considered a temporary measure until the allocation-based receipts are replaced with receipts based on Vector transfers.

Network Subgraph Indexing

So far, indexers had to rely on https://gateway.network.thegraph.com/network to provide network subgraph data like allocations, subgraph deployments and more. With this release, indexers can index this network subgraph themselves and still fall back to https://gateway.network.thegraph.com/network if this subgraph hasn't fully synced yet or has failed locally.

In order to achieve this, the following infrastructure changes need to be applied:

  • Indexer agent now exports an HTTP server at port 8002. This needs to be made available to the indexer service.
  • Indexer agent needs to have the following configuration set:
    • INDEXER_AGENT_NETWORK_SUBGRAPH_ENDPOINT=https://gateway.network.thegraph.com/network (alternative: --network-subgraph-endpoint)
    • INDEXER_AGENT_NETWORK_SUBGRAPH_DEPLOYMENT=QmaUBw7sr8pBrwNgz6JkbmmGoUU7KJSaeRvCaY3NPDbQ7A (alternative: --network-subgraph-deployment)
  • Indexer service needs to have the following configuration set:
    • INDEXER_SERVICE_NETWORK_SUBGRAPH_ENDPOINT=http://indexer-agent:8002/network (alternative: --network-subgraph-endpoint)

This will make the agent index the network subgraph itself and serve it at :8002/network by default (this can be changed with --syncing-port), falling back to the gateway endpoint if there are any problems with the network subgraph. The service will then query the network subgraph through the agent.

Changes (Per Component)

Indexer Agent

Fixed

  • Make receipts table renaming migration more robust

Added

  • Allow network subgraph endpoint to be used as a fallback for the local network subgraph deployment
  • Add allocation exchange contract address for mainnet

Changed

  • Rename query fee related fields in database models

Indexer CLI

  • Fix bug that could cause AsyncCache to fail perpetually

Indexer Native

  • Only sync database models in the agent to avoid race conditions
  • Rename X-Graph-Payment header to Scalar-Receipt

docker pull ghcr.io/graphprotocol/indexer-service:v0.14.0

Changes (Overview)

The main change in this release is the (temporary) replacement of Vector as the base layer of Scalar with allocation-base receipts. We will continue working on the Vector integration and plan to transition to Vector as soon as possible, but we first wanted to unblock our launch partners going live on mainnet.

At a high level this means:

  • Scalar receipts will, for now, be created against allocations, not Vector transfers.
  • Indexers will (for the moment) not need to run a Vector node.
  • Receipts are collected via a /collect-receipts endpoint on the gateways. This will convert them into a signed (query fee) voucher that can then be redeemed via a new AllocationExchange contract.

With this release, the indexer infrastructure changes as follows:

  • The Vector node is removed.
  • A new INDEXER_AGENT_COLLECT_RECEIPTS_ENDPOINT / --collect-receipts-endpoint configuration option is added to Indexer Agent to configure the endpoint that converts bundles of receipts into query fee vouchers.
  • A new INDEXER_SERVICE_CLIENT_SIGNER_ADDRESS / --client-signer-address configuration option is added to Indexer Service to configure the signer of the incoming receipts. For now, this limits indexers to being able to serve a single client. As a temporary change, this feels acceptable. Transitioning back to Vector will remove this limitation again.
