Fix notification cache paging with snowflake-like ids (!885) · Merge requests · hive / hivemind

Notification cache id is changed to snowflake-like id, which is concatenation of the following fields:

sign bit     1 bit
timestamp    35 bits
type_id      6 bits
counter      22 bits

timestamp is offset to start at 2016-03-24T16:00:00, which is the HIVE_GENESIS_TIME. 35 bits is enough for 1000 years, since we only use seconds:

log2(1e3365.25246060) = ~34.87726843940377862696

This makes the IDs both deterministic and sortable.

Notification IDs are now always returned as strings by API, so that JSON parsers won't treat them as floats.
