Apache Impala

The Apache Impala Connector is a powerful tool that allows you to connect with live data to open source Apache Impala analyze the data directly in Tableau

Connector contains an embedded SQL Engine that pushes supported SQL operations to the data source and processes unsupported operations client-side (Query Folding):

• Issue complex queries using SQL-92 compliant operations and clauses.
• Leverage server-side data processing for supported operations.
• Build new relationships and custom datasets.

Connector supports bulk operations, push-down, client functions, aggregation and advanced TLS/SSL data encryption.
