Have you given https://apple.github.io/foundationdb/time-series.html https://apple.github.io/foundationdb/time-series.html a read? Since FoundationDB is lexicographically sorted it's pretty straight forward to keep things sorted for reading data in chronological order.
For example, if you want to read "last 5 minutes" of data, you can keep your timestamp at the end of the key in reverse order (Long.MaxValue - timestamp).
- lykr0n 8y agoYeah, but that doc assumes you've read and understood everything else in the docs. That document provides no help in understanding the database, it's concepts, or how to implement them. I could try and reconcile that doc with the python tutorial and everything else, but I just want something where I can copy and paste and it works. FoundationDB doesn't have a batteries included documentation like Clickhouse does: https://clickhouse.yandex/tutorial.html https://clickhouse.yandex/tutorial.html
