Apologies let me clarify: Pushshift has a live api that mirrors reddit which you can use to compile a more recent dataset[0].

The uploader of that BQ has cited Pushshift as their source[1].

PS: In the next couple of days the batched archive data for Q4 of 2019 as well as Q1 of 2020 will be available[2]
