Functions for applying and rolling back migrations.
applied-migrationsclj
(applied-migrations store index)List all migrations in the index that are applied to the database.

into-indexclj
(into-index migrations)(into-index index migrations)Add migrations to a map, using their :id as the key.

migrateclj
(migrate store migration)Apply a single migration to a data store.

migrate-allclj
(migrate-all store index migrations)(migrate-all store index migrations options)Migrate a data store with the supplied index and migration sequence. The index matches IDs in the data store with their associated migrations. The migrations should be a sequential collection in the order in which they should be applied to the database.
An additional map of options may be supplied that contains the following keys:
: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.
