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.

1.0.021 May 2015 00:25 major feature: Create an abstraction for repeated value vectors. Ensure DrillScanRel differentiates skip-all, scan-all scan-some in a backward compatible fashion. ScanBatch throws a NullPointerException instead of returning OUT_OF_MEMORY. AbstractRecordBatch.buildSchema() should properly handle OUT_OF_MEMORY outcome. Add support for context UDFs: user (and its synonyms session_user, system_user) and current_schema. RootExec implementations should properly handle IterOutcome.OUT_OF_MEMORY. properly handle OutOfMemoryException. AllocationHelper.allocateNew() doesn't have a consistent behavior when it can't allocate.
