stellar/go horizon-v22.0.0-rc1

Horizon v22.0.0-rc1

on GitHub

This is the release candidate for Protocol 22

Breaking Changes

• --parallel-job-size configuration parameter for the stellar-horizon db reingest command has been removed.
  Job size will be automatically determined based on the number of workers (configuration parameter --parallel-workers), distributing
  the range equally among them. The minimum job size will remain 64 ledgers and the start and end ledger range will be rounded to
  the nearest checkpoint. (5484)

• Removed num_accounts and amount fields from Asset stats related endpoints, and valid_before and valid_after fields from transaction related endpoints. Issue - 5438, PR - 5478

  • These fields have already been functionally deprecated as of release v2.1.0. As a part of this release, these fields are omitted from API Response
  • Additionally, the num_accounts and amount columns have been dropped from exp_asset_stats table in Postgres.

• Renamed errorResultXdr field to error_result_xdr in the response of the async transaction submission endpoint, POST /transactions_async. (5445)

Added

• Added response for new constructor functionality (introduced in protocol 22) in invoke host function operation (5488).

• Add metrics which give insight into how long it takes for ingestion to startup (5449).

Fixed

• Fixed the error field nested in the extras field in the response of the async transaction submission endpoint POST /transactions_async. (5440)

• Improved performance of requests which query the lower boundary of horizon's history when running a horizon instance with the --history-retention-count flag. (5410, 5448, 5465)

• Improve performance of ingestion when running horizon with the --history-retention-count flag by executing reaping of history lookup tables concurrently with ingestion. (5405)

• Improve performance of ingestion when consuming ledgers via the BufferedStorageBackend. (5494)
