Load any migrations EDN files in the path resource directory. A migration file ends with the .edn extension and contains a map with an :up and :down key.

Run any migrations that haven’t been executed yet. An optional datasource can be provided, defaults to gungnir.database/*datasource*.

opts takes the following arguments:

:strategy - defines what to do if there are conflicts between the migrations applied to the data store, and the migrations that need to be applied. The default strategy is ragtime.strategy/raise-error. :reporter - a function that takes three arguments: the store, the operation (:up or :down) and the migration ID. The reporter is a side-effectful callback that can be used to print or report on the migrations as they are applied. The default reporter is ragtime.reporter/silent.

Rollback the last run migration from migrations. An optional datasource can be provided, defaults to gungnir.database/*datasource*.
