[postgis-users] Geoprocessing & BigData

2016-01-18 Thread Ravi Pavuluri
Hi All, I am checking if there is a way to process quickly large datasets such as census blocks in PostGIS and also by leveraging big data platform. I have few questions in this regard. 1) When I try intersect for sample census blocks with another polygon layer, PostGIS 2.2(on Postgres 9.4)

Hey, if you have one beefy server you can parallelize throwing several queries working on sub set of your data. (aka parallel processing trough data partition). One conceptual example : you want to process the world, you create 20 workers, a list of countries, and then make the worker process the
