Apache Drill 1.0.0

Apache Drill allows to query non-relational datastores. It supports HBase, MongoDB, MapR-DB, HDFS, MapR-FS, Amazon S3, Azure Blob Storage, Google Cloud Storage, Swift, NAS and local files. The aggregation and query mechanism even allows to join across multiple database backends. The query plan optimizer is datastore-aware and utilizes individual NoSQL filter and query mechanisms depending on each backend scheme.
