Accumulo data model always works with single table. However, its schema definition is flexible enough interpret to define "merged" tables depending upon the foreign key relationships defined in Teiid schema.

See section 7.4 in https://accumulo.apache.org/1.5/accumulo_user_manual.html

This will lead to providing some limited JOIN based queries on Accumulo with Teiid. This is similar to functionality in the MongoDB translator.
