新機能

New Features in Apache Impala

今回は大きな機能追加はないようですが、テクニカルプレビューの Automatic Metadata Sync using Hive Metastore Notification Events機能は興味深いです。

When enabled, the catalogd polls Hive Metastore (HMS) notifications events at a configurable interval and syncs with HMS. You can use the new web UI pages of the catalogd to check the state of the automatic invalidate event processor.
