This includes the new profile fetched_at logic and reaction stats.
When receiving new profiles, nostrdb will record when it was last
received in a new database. This database is a mapping from Pubkey to
timestamp.
You can manually read/write to this table using:
ndb_read_last_profile_fetch
ndb_write_last_profile_fetch
This patch also includes the new reaction counting metadata table. It is
not used yet (but reactions are still counted!)
Changelog-Added: Added reaction counters to nostrdb
Changelog-Added: Record when profile is last fetched in nostrdb
Timestamped IDs were not being initialized properly when writing profile
indices. This means that every profile was indexed with timestamp 0.
derp. Fix this!
Changelog-Fixed: Fix profiles not updating
This is a refactor of the codebase to use a more memory-efficient
representation of notes. It should also be much faster at decoding since
we're using a custom C json parser now.
Changelog-Changed: Improved memory usage and performance when processing events
Since we can't mutate NdbNotes, let's update the existing codebase to
generate and sign ids on NostrEvent constructions. This will allow us to
match NdbNote's constructor
