It allows easy manipulation of structured data with high performances. It is very easy to install the Neo4j Community edition and connect to it
which makes it impossible to draw any conclusions about the performance of Neo4j at a larger scale. Since the sourcing CSV data is effectively already partitioned by year and month, what this operation effectively does is pipe the CSV file through a data frame transformation and then into it’s own partition in a larger, combined data frame. As a result, the partitioning has greatly sped up the query bit reducing the amount of data that needs to be deserialized from disk. This fact can be taken advantage of with a data set partitioned by year in that only data from the partitions for the targeted years will be read when calculating the query’s results. Copyright © 2016 by Michael F. Kamprath. I am sure these figures can be improved by: But this would be follow-up post on its own.
