The key new ingredients of ELT/EDW in the Big Data era are the radical increase in unstructured data and the introduction of fast data into the equation.
- Faster response times for ad hoc queries and large scale joins executed via Spark SQL
- Rapid massive data ingest from Hadoop HDFS, Amazon S3, and Apache Kafka
- Hyper-accelerated data/document parsing of JSON, CSV, Parquet and Avro data
- Accelerated ELT, data cleansing, and data enrichment processes in Spark
