Do you use encoding like delta-of-delta timestamps or something similar?

I don't follow. Why don't you require indexes where other databases do?

Thanks.

We don't store deltas, timestamps are stored as 64-bit int back to back in column. So are other primitives actually.

To avoid using indexes we store timestamps in ascending order. Timestamp interval search uses partitioning to cull chunks of data before lifting data in memory. Once in memory we use binary search on ordered timestamps to find intervals.

That said we do support indexes for key-based lookups
