  3. How we made geo joins 400× faster with H3 indexes from floedb.ai
    89 by matheusalmeida 1d ago | | |

    Article: 14 min

    This article discusses how the Floe system automatically optimizes geo joins for faster performance using H3 indexes, resulting in a 400× speedup.

    This optimization can lead to more efficient data processing in industries that rely on spatial queries, such as GIS and location-based services.
    • Floe system automatically rewrites geo joins to use H3 indexes for faster execution.
    • H3 indexes provide hierarchical resolution and compact keys, allowing efficient set operations.
    • The rewrite reduces the number of candidates by approximating shapes with cell IDs, leading to a significant speedup.

    Discussion (20): 5 min

    The discussion revolves around the suitability of discrete global grid systems (DGGS) for analytical computation, specifically comparing H3 and S2. The main points include the importance of congruency in DGGS for efficient spatial joins, limitations of H3 due to its visualization optimization, and the potential of S2 as a system that straddles both analytics and visualization capabilities. Participants also share experiences with alternative indexing strategies using tools like Elasticsearch and geohashes.

    • H3 is not suitable for analytical computation due to the lack of congruency
    • S2 straddles the analytics and visualization property space, being not particularly good at either
    Counterarguments:
    • The lack of congruency issue is related to rendering geometry rather than the index itself.

    • Isn't this his personal blog? The domain name is 'stephenwolfram.com', this is his personal website. Of course there will be 'I''s and 'me''s — this website is about him and what he does.
    • That's his style. It's not just his blog style, it's the same in his book.
