hakunapi - FlatGeoBufs as data source
We've added FlatGeobuf read support to hakunapi. The implementation supports full OGC API Features compliance including CQL2 filtering, with configuration as simple as pointing to a .fgb file - local or remote.
Key practical benefits include excellent local file performance via memory-mapped I/O and spatial indexing, plus HTTP range request support for querying remote files directly from object storage. Schema discovery is automatic, and hakunapi's streaming architecture keeps memory overhead minimal.
For read-heavy workloads with infrequent updates, this offers a leaner, faster alternative to popular solutions with significantly lower runtime overhead. It's suited for publishing authoritative datasets where operational simplicity and performance matter.
