SQL-on-Accumulo with Pivotal HAWQ and PXF

Back to Schedule



APIs / Frameworks


Pivotal Xtension Framework (PXF) support for Accumulo within HAWQ provides a fully-featured and native SQL interface to data stored in Accumulo. The Accumulo/PXF module works by intelligently extracting data from Accumulo through iterators and the Accumulo APIs to deliver data to HAWQ's SQL execution engine. Data extraction is fully parallel and utilizes query predicate push downs for an additional performance boost. Additionally, it natively supports Accumulo's security labels functionality.

PXF is an external table interface in HAWQ, a SQL-on-Hadoop system, which allows you to read data stored within the Hadoop ecosystem. External tables can be used to load data into HAWQ from Hadoop and/or also query Hadoop data without materializing it into HAWQ PXF enables analysis of HAWQ data and Hadoop data in a single query. It supports a wide range of data formats such as Text, AVRO, Hive, Sequence, RCFile formats, HBase, and now Accumulo.
