I have some questions about defining a series of bits in Golang
For (3), and if you’re interested in checking if specific bits are set or not, take a look at https://github.com/bits-and-blooms/bitset and https://github.com/RoaringBitmap/roaring.
- Bitmasks - how and why to use?

Skipfilter
Each topic has a roaring bitmap. Each bit corresponds to a subscriber in the skip list. For each topic, head and tail cursors are also maintained to ensure that newly added subscriptions are always tested and deleted subscriptions are always evicted. Roaring bitmaps are compressed and discontinuous so memory usage again remains bounded as subscribers come and go.

Bit shifting blew my mind
Definitely take a look at a roaring bitmap. https://github.com/RoaringBitmap/roaring

Protocol buffers database, a Key-Value database on the wire
Roaring bitmaps + btrees are a rock solid indexing approach. Alternatively, bleve has a lot out of the box but that's introducing a new datastore, basically.
