Re: [geomesa-users] Question on accelerating 'join' process
|
Hello,
Since you're doing a point-in-polygon join with a limited number of
polygons, your best approach is likely to convert the polygons into
filters and use them to query the points layer. That way, you'll
leverage the index structures to only query the data you want.
Otherwise, you could use a brute force approach in spark using a
broadcast join.
Thanks,
Emilio

Hi, we are dealing with location-based data(1Tb per
day) using Point as index. The job is to join one thousand
areas(Polygon or MultiPolygon) with these location-based points
to determine whether a point is inside one of these areas. We
are wondering what is the fastest way to finish this join
process? Thank you!
Best Regards,
Evan
