Known Issues
The following are known issues that you may encounter due to limitations in the data source, the connector, or an application
- [IMP-843][00294390] Limited support for query translation The connector does not support query translation if the query contains the "LIMIT x OFFSET y" syntax.
- Limited support for BINARY, DATE, and TIME data types
- BINARY is not a supported data type in Impala
- DATE is supported only when you connect to Impala version 3.3 or later
- As a result of the limitations above, some values of TIME data types are also not supported.
