Horizon v22.0.1

Fixed

• Fix the issue where the skip-txmeta flag is not being applied in /transactions/{tx-id} endpoint (5523).
• Fix horizon_ingest_reap_lookup_tables_duration_seconds metric which reports the total number of lookup table rows which were reaped (5528).

Removed

• Removed defunct init-genesis-state command (5504).

Galexie v22.0.0

• Add support for Protocol 22

• Improve performance of XDR encoding / decoding (#5494)

Horizon v22.0.0

This release adds support 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.

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).

• Added error_result_xdr field in the response of the async transaction submission endpoint, POST /transactions_async. error_result_xdr should be used instead of errorResultXdr which is now deprecated. (5445)

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)

Deprecations

• The errorResultXdr field from the response of the async transaction submission endpoint has been deprecated and will be removed in the v23 release. (5496)
• The num_archived_contracts and archived_contracts_amount fields from the /assets response have been deprecated and will be removed in the v23 Horizon release. (5496)

Galexie v22.0.0-rc1

• Add support for Protocol 22

• Improve performance of XDR encoding / decoding (#5494)

Horizon v22.0.0-rc2

This release adds support for Protocol 22

Deprecations

• The errorResultXdr field from the response of the async transaction submission endpoint has been temporarily reinstated. However it will be removed in the v23 release. (5496)
• The num_archived_contracts and archived_contracts_amount fields from the /assets response have been deprecated and will be removed in the v23 Horizon release. (5496)

Horizon v22.0.0-rc1

Galexie v1.0.0

🎉 The First Release of Galexie (Ledger Exporter) 🎉

Galexie is a lightweight application designed to bundle, process, and store Stellar network data in an external data store. It offers the following features:

• 🔍 Data Extraction: Extracts raw ledger data from the Stellar network.
• 📦 Compression: Compresses raw data for efficient storage.
• 💾 Storage Options: Supports various storage solutions, starting with Google Cloud Storage (GCS).
• ⚙️ Modes of Operation: Can operate in either batch mode or streaming mode.

Want to run your own Galexie instance? 🚀 Check out the Admin Guide for setup instructions 📚. Grab the Docker image here 🐳 !

Horizon v2.32.0

Added

• Reingest from pre-computed tx meta on remote cloud storage. (4911), (5374)
  • Configure horizon reingestion to obtain ledger tx meta in pre-computed files from a Google Cloud Storage(GCS) location.
  • Using this option will no longer require a captive core binary be present and it no longer runs a captive core sub-process, instead obtaining the tx meta from the GCS backend.
  • Horizon supports this new feature with two new parameters ledgerbackend and datastore-config on the reingest command. Refer to Reingestion README.
• Add metrics for reaping of history lookup tables (5385).
• Add --reap-lookup-tables (defaults to true) which will disable reaping of history lookup tables when set to false. (5366).

Fixed

• Fix ingestion duration metric so it includes time spent reaping history lookup tables (5361).
• Optimize query for reaping history lookup tables (5393).

Horizon v2.31.0

2.31.0

What's Changed

If you are using a custom captive-core config and setting Horizon CAPTIVE_CORE_USE_DB=false, then need to make sure to set EXPERIMENTAL_BUCKETLIST_DB=false in the captive core config toml to be compatible with stellar-core versions 21 and earlier

Breaking Changes

• Change ingestion filtering logic to store transactions if any filter matches on it. (5303)
  • The previous behaviour was to store a tx only if both asset and account filters match together. So even if a tx matched an account filter but failed to match an asset filter, it would not be stored by Horizon.
• Captive-core configuration parameters updated to align with stellar-core v21 (5333)
  • BucketlistDB is now the default database for stellar-core, deprecating the usage of EXPERIMENTAL_BUCKETLIST_DB in captive core configuration toml.
  • A new mandatory parameter DEPRECATED_SQL_LEDGER_STATE (default: false) is required by stellar-core on its captive core configuration toml file. if the toml provided by CAPTIVE_CORE_CONFIG_PATH does not have this new setting, Horizon will add it automatically, therefore, no action required.
  • If using EXPERIMENTAL_BUCKETLIST_DB_INDEX_PAGE_SIZE_EXPONENT or EXPERIMENTAL_BUCKETLIST_DB_INDEX_CUTOFF in captive core configuration toml, they must be renamed to BUCKETLIST_DB_INDEX_PAGE_SIZE_EXPONENT and BUCKETLIST_DB_INDEX_CUTOFF respectively.

Added

• Bump XDR definitions (5289), (5330)
• Add new async transaction submission endpoint (5188)
• Add horizon_ingest_errors_total metric key (5302)
• Add transaction hash to txsub timeout response (5328)
• Add new captive-core flags for V1 Meta (5309)
• Add version check for protocol 21 (5346)
• Improve horizon history reaper (5331). New reaper configuration flags REAP_FREQUENCY - the frequency in units of ledgers for how often history is reaped.

Fixed

• Fix the following ingestion error: error preparing range: error starting prepare range: the previous Stellar-Core instance is still running (5307)
