Release Notes

1.0.0 - Added value to the existing libraries (clj-spark and flambo)

• It's about twice as fast by getting rid of a reflection call (thanks to David Jacot for his take on this).
• Get rid of mapping/remapping inside the api functions, which
  • bloated the execution plan (mine shrinked to a third) and
  • (more importantly) allowed me to keep partitioner information.
• adding more -values functions (e.g. map-values), againt to keep partitioner information.
• Additional Sources for RDDs:
  • JdbcRDD: Reading Data from your JDBC source.
  • Hadoop-Avro-Reader: Reading AVRO Files from HDFS
