Document spatial Left Join #2560
Description
Based on this discussion about spatial joins, I have tried various options to perform a spatial left join.
Currently, we were using the S2 or H3 strategy as we need to perform LEFT JOINs in our setup (not inner joins). However, we figured out a combination of INNER JOIN and a FULL OUTER JOIN to produce a result of a LEFT JOIN by keeping high performance of Sedona spatial join.
A documentation will be updated in the PR.
