widerow

This is an open source project!

Description

WideRow is a high level API for dealing with Cassandra wide-rows as if they were lazy collections. While primarily meant for Cassandra, the WideRow API is database and driver agnostic.

Key features:

• Chaining of multiple rows into one logical sequence
• Supports collection methods like map(), flatMap(), filter(), collect(), and group()
• Conservative querying to minimize data reads
• Fast querying to fetch data concurrently
