Version 2.2.0 v2
Enhancements, bug fixes, and other changes in Hadoop Foreign Data Wrapper 2.2 include:
| Type | Description |
|---|---|
| Feature | Push down aggregates to remote HDFS servers: Push aggregates to the remote HDFS server instead of fetching all of the rows and aggregating them locally. This gives a performance boost for cases where aggregates can be pushed down. |
| Enhancement | Add support for NUMERIC data type. |
| Bug fix | Do not push expressions evaluating as non-builtin data types. |
