Ohioedge Persistence API for Cassandra (OPAC) is an object-relational mapping Java Driver for C*. OPAC enables definition-driven management of C* db objects (schema, table, materialized view and constraint) and provides out-of-the-box zero-code data retrieval, creation, update and deletion (CRUD) functionality for the defined objects. OPAC maximizes performance by utilizing multi-threading for entity relationship building and by retrieving only the minimally required columns of the intermediate entities. OPAC is built on top of DataStax Java Driver.
