DeltaSourceSnapshot

class DeltaSourceSnapshot extends StateCache

Converts a Snapshot into the initial set of files read when starting a new streaming query. The list of files that represent the table at the time the query starts are selected by: - Adding version and index to each file to enable splitting of the initial state into multiple batches. - Filtering files that don't match partition predicates, while preserving the aforementioned indexing.
