Using other Cascading tools

The Cascading ecosphere is expanding rapidly and there are many toolsets and extensions that can help you with common tasks. Let's take a look at a few of them. Many of these are available for download from the previous URLs.

Lingual

Lingual is a Cascading framework tool that allows ANSI standard SQL queries to be used to create, transform, and move data. Lingual is based on the Apache Calcite framework (formerly known as Optiq). Essentially, using Lingual, one can write complex workflows as SQL commands, and then they are translated into Cascading flows, taps, and so on. Since Cascading interoperates with Hadoop, this allows ingestion and storage of Hadoop resident data through this programming paradigm.

This use pattern is very similar to Hive. However, Lingual is Cascading-specific and can therefore interoperate with Cascalog, Scalding, and Java. One other advantage over Hive is that using Cascading as an insulating layer, these programs will be able to more quickly...
