cardano-db-sync

cardano-db-sync Overview

The cardano-db-sync component consists of a set of components:

  • cardano-db which defines common data types and functions used by any application that needs to interact with the data base from Haskell. In particular, it defines the database schema.

  • cardano-db-sync which acts as a Cardano node, following the chain and inserting data from the chain into a PostgreSQL database.

  • cardano-db-sync-extended is a relatively simple extension to cardano-db-sync which maintains an extra table containing epoch data.

The two versions cardano-db-sync and cardano-db-sync-extended are fully compatible and use identical database schema. The only difference is that the extended version maintains an Epoch table. The non-extended version will still create this table but will not maintain it.
