Well-known sink type identifiers for Chronicle projections and reducers.

Use these atoms as the :default_sink_type_id option when starting Chronicle.Client. The default is :mongodb.

Available types

• :mongodb — persists read models into MongoDB (default)
• :sql — persists read models into a SQL database
• :in_memory — persists read models in memory only
• :none — no sink configured (used by passive projections)

Example

{Chronicle.Client,
  connection_string: "chronicle://localhost:35000?disableTls=true",
  event_store: "my-store",
  default_sink_type_id: :sql,
  read_models: [MyApp.ReadModels.Account]}
