IMPORTANT: Database migration

This version includes a significant database migration which changes the column types of fee_charged and max_fee in the history_transactions table from integer to bigint. This essential change paves the way for fee bump transactions (CAP 15), a major improvement that will be released soon in Stellar Protocol 13.

This migration will run for a long time, especially if you have a Horizon database with full history. For reference, it took around 8 hours and 42 minutes to complete this migration on a AWS db.r4.xlarge instance with full transaction history.

To execute the migration run horizon db migrate up using the Horizon v1.1.0 binary.

Important Note: Horizon should not be serving requests or ingesting while the migration is running. For service continuity, if you run a production Horizon deployment it is recommended that you perform the migration on a second instance and then switch over.

Changes

  • DB: Remove unnecessary duplicate indexes: index_history_transactions_on_id, index_history_ledgers_on_id, exp_asset_stats_by_code, and asset_by_code (#2419).
  • DB: Remove asset_stats table which is no longer necessary (#2419).
  • Validate transaction hash IDs as 64 lowercase hex chars. As such, wrongly-formatted parameters which used to cause 404 (Not found) errors will now cause 400 (Bad request) HTTP errors (#2394).
  • Fix ask and bid price levels of GET /order_book when encountering non-canonical price values. The limit parameter is now respected and levels are coallesced properly. Also, price_r is now in canonical form (#2400).
  • Added missing top-level HAL links to the GET / response (#2407).
  • Full transaction details are now included in the POST /transactions response. If you submit a transaction and it succeeds, the response will match the GET /transactions/{hash} response (#2406).
  • The following attributes are now included in the transaction resource:
    • fee_account (the account which paid the transaction fee)
    • fee_bump_transaction (only present in Protocol 13 fee bump transactions)
    • inner_transaction (only present in Protocol 13 fee bump transactions) (#2406).
  • Add support for CAP0018: Fine-Grained Control of Authorization (Protocol 13) (#2423).
    • Add is_authorized_to_maintain_liabilities to Balance.
