In this commit, we add a new storage namespace to channeldb: the ForwardingLog. This log will be used by higher level sub-systems to log each successfully completed HTLC. Each payment circuit will be summarized as a “ForwardingEvent”. A series of events can then be queried via a time slice query. In a time slice query, the caller specifies a time range, a number of events to skip, and the max number of events to return. Each query will return the index of the final item. As we have a max number of events we’ll return in a response, callers may need to use this last offset index to seek further by skipping that number of entries. Combining these fields, callers are able to query the time series, skipping an arbitrary amount of events, and capping the max number of returned events.
