stellar/go horizon-v1.6.0

Horizon 1.6.0

on GitHub

• Add --parallel-workers and --parallel-job-size to horizon db reingest range. --parallel-workers will parallelize reingestion using the supplied number of workers. (#2724)
• Remove Stellar Core's database dependency for non-ingesting instances of Horizon. (#2759)
  Horizon doesn't require access to a Stellar Core database if it is only serving HTTP request, this allows the separation of front-end and ingesting instances.
  The following config parameters were removed:
  • core-db-max-open-connections
  • core-db-max-idle-connections
• HAL response population is implemented using Go strings package instead of regexp, improving its performance. (#2806)
• Fix a bug in POST /transactions that could cause tx_bad_seq errors instead of processing a valid transaction. (#2805)
• The --connection-timeout param is ignored in POST /transactions. The requests sent to that endpoint will always timeout after 30 seconds. (#2818)

Experimental

• Add experimental support for live ingestion using a Stellar Core subprocess instead of a persistent Stellar Core database.

  Stellar-core now contains an experimental feature which allows replaying ledger's metadata in-memory. This feature starts paving the way to remove the dependency between Stellar Core's database and Horizon. Requires Stellar Core v13.2.0.

  To try out this new experimental feature, you need to specify the following parameters when starting ingesting Horizon instance:

  • --enable-captive-core-ingestion or ENABLE_CAPTIVE_CORE_INGESTION=true.
  • --stellar-core-binary-path or STELLAR_CORE_BINARY_PATH.
