Data Model
The provider models Apache Impala instances as relational databases. The provider leverages the Impala Server Thrift API, to enable bidirectional access to Apache Impala data through SQL. Impala Server 2.2.0 and above are supported.
Discovering Schemas
The CData ADO.NET Provider for Apache Impala dynamically obtains the Apache Impala schemas. Reconnect to load any changes in the metadata, such as added or removed columns or changes in data type.
