Apache Accumulo is a highly scalable, distributed, open source data store modeled after Google’s Bigtable design. Accumulo is built to store up to trillions of data elements and keeps them organized so that users can perform fast lookups. Accumulo supports flexible data schemas and scales horizontally across thousands of machines. Applications built on Accumulo are capable of serving a large number of users and can process many requests per second, making Accumulo an ideal choice for terabyte- to petabyte-scale projects.
