Big data gets a new open-source project: Apache Arrow

The Apache Software Foundation on Wednesday launched Arrow as a top-level project designed to provide a high-performance data layer for columnar in-memory analytics across disparate systems.

Based on code from the related Apache Drill project, Apache Arrow can bring benefits including performance improvements of more than 100x on analytical workloads, the foundation said. In general, it enables multi-system workloads by eliminating cross-system communication overhead.

Code committers to the project include developers from other Apache big-data projects such as Calcite, Cassandra, Drill, Hadoop, HBase, Impala, Kudu, Parquet, Phoenix, Spark and Storm.

"The open-source community has joined forces on Apache Arrow," said Jacques Nadeau, vice president of the new project as well as Apache Drill. "We anticipate the majority of the world's data will be processed through Arrow within the next few years."

In many workloads, between 70 percent and 80 percent of CPU cycles are spent serializing and deserializing data. Arrow alleviates that burden by enabling data to be shared among systems and processed with no serialization, deserialization or memory copies, the foundation said.

"An industry-standard columnar in-memory data layer enables users to combine multiple systems, applications and programming languages in a single workload without the usual overhead," said Ted Dunning, vice president of the Apache Incubator and member of the Apache Arrow Project Management Committee.

Arrow also supports complex data with dynamic schemas in addition to traditional relational data. For instance, it can handle JSON data, which is commonly used in Internet-of-Things (IoT) workloads, modern applications and log files. Implementations are also available for a number of programming languages for greater interoperability.

Apache Arrow software is available under the Apache License v2.0 and is overseen by a self-selected team of active contributors to the project.
