对于关注Open sourc的读者来说，掌握以下几个核心要点将有助于更全面地理解当前局势。
首先，Lamport’s derivation of Paxos illustrates this beautifully. He begins with the simplest specification of consensus: chosen starts as the empty set and transitions to a singleton {v}. That is the entire next-state formula. He then refines to a voting algorithm where acceptors vote and a value is chosen if a majority votes for it, and refines further to Paxos to handle the problems that arise (what if N acceptors vote for v1, N for v2, and the remaining acceptor fails?). At each refinement step, the guards become more local. In Paxos, the guard for whether an acceptor should cast a vote depends on local knowledge: what ballots this acceptor has participated in. The monotonic structure of ballot numbers ensures that this local knowledge does not become invalid: once an acceptor knows something about the progress of voting, that fact is permanent. This is what makes Paxos work despite asynchrony and failures.

其次，})Grouping and aggregatingGrouping behaves somewhat unconventionally in tablecloth. Datasets can be grouped by a single column name or a sequence of column names like in other libraries, but grouping can also be done using any arbitrary function. Grouping in tablecloth also returns a new dataset, similar to dplyr, rather than an abstract intermediate object (as in pandas and polars). Grouped datasets have three columns, (name of the group, group id, and a column containing a new dataset of the grouped data). Once a dataset is grouped, the group values can be aggregated in a variety of ways. Here are a few examples, with comparisons between libraries:
