Index factories

DipDup allows creating new indexes in runtime. To begin with, you need to define index templates in the top-level templates section of the config. Then call ctx.add_contract and ctx.add_index methods from any user callback.

The most common way to spawn indexes is to create an index that tracks the originations of contracts with similar code or originated by a specific contract. A minimal example looks like this:

contracts:
  registry:
    address: KT19CF3KKrvdW77ttFomCuin2k4uAVkryYqh

indexes:
  factory:
    kind: operation
    datasource: tzkt
    types:
      - origination
    handlers:
      - callback: on_factory_origination
        pattern:
          - type: origination
            similar_to: registry

Another solution is to implement custom logic in on_restart hook (see 5.3. Event hooks → on_restart)
