I want to generate a map, using some spatial data provider like OSM. I am trying to put in some dynamic data-set on top of the base map. The data size is considerably large enough to be called as BigData. Its taking hours to insert data into PostGIS. NoSQL Databases are meant to be scalable for humongous data sets. So my query is can i replace my PostGIS database with NoSQL, considering the scale-out factor and the enormous growth of data.
If so which seems best MongoDB, Hbase or Neo4j.
