ParticipantPruningServiceGrpc.AsyncService
Prunes/truncates the “oldest” transactions from the participant (the participant Ledger Api Server plus any other participant-local state) by removing a portion of the ledger in such a way that the set of future, allowed commands are not affected. This enables: 1. keeping the “inactive” portion of the ledger to a manageable size and 2. removing inactive state to honor the right to be forgotten.
