The presented function will work for from microsecond- to century-long intervals. The one downside would be that leap years will make time stamps over long periods look less nice and solving for that would make the proposed function much more complicated as you can imagine by observing gregorian calendar time shifting: Spark DataFrame is simply not a good choice for an operation like this one. In general SQL primitives won't be expressive enough and PySpark DataFrame doesn't provide low level access required to implement it. While re-sampling can be easily represented using epoch / timestamp arithmetics. With data like this: import org. apache. spark.

Python Spark Shell Prerequisites. Prerequisite is that Apache Spark is already installed on your local machine. This post has demonstrated how to pivot and resample time series in Pandas and Spark. The data used for this exercise is real measurements of energy production in Switzerland. The resampled data shows evidence of where nuclear power plant and renewable energy sources are located. To understand what’s going on in the above pipeline, read the corresponding type field of the each pipeline step. In our case: singleband.spatial.read.s3 – load tiles into Spark memory as (ProjectedExtent, Tile) tuples; singleband.spatial.transform.tile-to-layout – tile and index data as (SpatialKey, Tile) tuples; singleband.spatial.transform.buffered-reproject – reproject everything (case class) Write geotrellis.spark.pipeline.ast.singleband.
