Open source projects using Accumulo

Apache Fluo

Fluo builds on Accumulo and enables low latency, continuous incremental processing of big data.

Apache Gora

Gora open source framework provides an in-memory data model and persistence for big data. Accumulo’s continuous ingest test suite was adapted to Gora and called Goraci.

Apache Hive

Hive data warehouse software facilitates reading, writing, and managing large datasets residing in distributed storage using SQL. Hive has the ability to read and write data in Accumulo using the AccumuloStorageHandler.

Apache Pig

Pig is a platform for analyzing large data sets that consists of a high-level language for expressing data analysis programs, coupled with infrastructure for evaluating these programs. Pig has the ability to read and write data in Accumulo using AccumuloStorage.

Apache Rya

Rya is a scalable RDF triple store built on top of a columnar index store.


D4M is an open source library for large-scale computation that supports graph, matrix, and relational processing. D4M includes an Accumulo connector, among others, to interface with and compute on data in Accumulo tables.


Gaffer is an open source framework for constructing and querying very large graphs based on a variety of data storage platforms, including Accumulo.


Geomesa is an open-source, distributed, spatio-temporal database built on a number of distributed cloud data storage systems, including Accumulo, HBase, Cassandra, and Kafka.


Geowave is a library for storage, index, and search of multi-dimensional data on top of a sorted key-value datastore.


Graphulo is a Java library for Apache Accumulo which delivers server-side sparse matrix math primitives that enable higher-level graph algorithms and analytics.


Presto is an open source distributed SQL query engine for running interactive analytic queries against data sources of all sizes, ranging from gigabytes to petabytes. Through the use of the new Accumulo connector for Presto, users are able to execute traditional SQL queries against new and existing tables in Accumulo. For more information, see the Accumulo Connector documentation.


Sharkbite is a native Key/Value client that supports direct Accumulo access without the need for a proxy.


Timely is a secure time series database based on Accumulo and Grafana.

Uno and Muchos

Uno and Muchos provide automation for quickly setting up Accumulo instances for testing. These project were created to enable Fluo testing, but can be used to setup just Accumulo.
