cardano-foundation/cardano-graphql 6.1.0

Cardano GraphQL 6.1.0

on GitHub

This minor release adds compatibility with cardano-db-sync@12 and cardano-node@1.31.0 , plus fixes a bug relating to Transaction.collateral.

Compatible with:

• cardano-node: 1.31.0
• cardano-ogmios: v4.2.1
• cardano-db-sync: 12.0.0 - Note: The database must be recreated using the new version.
• hasura/graphql-engine: 1.3.3

System Requirements

• DB Sync system requirements
  • The system requirements for cardano-db-sync (with both db-sync and the node running on the same machine are:
    • Any of the big well known Linux distributions (eg, Debian, Ubuntu, RHEL, CentOS, Arch etc).
    • 24 Gigabytes of RAM.
    • 4 CPU cores.
    • 80 Gigabytes or more of disk storage (preferably SSD which are 2-5 times faster than electro-mechanical disks).
  • The recommended configuration is to have the db-sync and the PostgreSQL server on the same machine. During syncing (getting historical data from the blockchain) there is a HUGE amount of data traffic between db-sync and the database. Traffic to a local database is significantly faster than traffic to a database on the LAN or remotely to another location.

The host machine will need at least 32 Gigabytes of RAM to run the full cardano-graphql stack.

Bug Fixes

• Add missing Transaction.collateral Hasura table config (8a5f93e)

Known Issues

• Submitting random string to the submitTransaction mutation hangs #545
