Highlights

This release drops support for Substreams RPC protocol sf.substreams.v1 and switch to Substreams RPC protocol sf.substreams.rpc.v2. As a end user, right now the transition is seamless. All StreamingFast endpoints have been updated to to support the legacy Substreams RPC protocol sf.substreams.v1 as well as the newer Substreams RPC protocol sf.substreams.rpc.v2.

Support for legacy Substreams RPC protocol sf.substreams.v1 is expected to end by June 6 2023. What this means is that you will need to update to at least this release if you are running substreams-sink-files in production. Otherwise, after this date, your current binary will stop working and will return errors that sf.substreams.v1.Blocks is not supported on the endpoint.

From a database and operator standpoint, this binary is fully backward compatible with your current schema. Updating to this binary will continue to sink just like if you used a prior release.

Retryable Errors

The errors coming from sink files handler are not retried anymore and will stop the binary immediately.

Added

  • Added --infinite-retry to never exit on error and retry indefinitely instead.

  • Added --development-mode to run in development mode.

    Warning You should use that flag for testing purposes, development mode drastically reduce performance you get from the server.

  • Added --final-blocks-only to only deal with final (irreversible) blocks.
