Data Model
The driver models Apache Impala instances as relational databases. The driver 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 ODBC Driver 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.
