Version 2.3.0 v2
Enhancements, bug fixes, and other changes in Hadoop Foreign Data Wrapper 2.3 include:
| Type | Description |
|---|---|
| Feature | When possible, we push the ORDER BY clause to the remote server. This approach provides the ordered result set from the foreign server, which can help to enable an efficient merge join. |
| Feature | Push down LIMIT/OFFSET to remote HDFS servers: Where possible, perform LIMIT and OFFSET operations on the remote server. This reduces network traffic between local Postgres and remote HDFS/Hive servers. |
