Open Distro for Elasticsearch 1.8.0 Release Notes

Open Distro for Elasticsearch 1.8.0 is now available for download.

The release consists of Apache 2 licensed Elasticsearch version 7.7.0, and Kibana version 7.7.0. Plugins in the distribution include alerting, index management, performance analyzer, security, SQL, and machine learning with k-NN and anomaly detection. SQL JDBC/ODBC driver, SQL CLI Client, and PerfTop, a client for Performance Analyzer are also available for download.

Release Highlights

  • The snapshot feature is now available in the Index Management plugin. This feature allows users to recover from failure and migrate indices from one cluster to another.
  • Anomaly Detection plugin releases the new count aggregation feature to detect anomalies.
  • New feature Cosine Similarity is available for use in k-NN plugin.
  • Support for connecting PerfTop CLI, a client for Performance Analyzer to clusters with basic authentication.

Release Details

The release includes the following features, enhancements, infrastructure and documentation updates, and bug fixes.

Breaking Changes

  • Artifact Name of Anomaly Detection Plugin for DEB and RPM distribution is updated from opendistro-anomaly-detector to opendistro-anomaly-detection. In order to reduce the impact of this change, we recommend removing the old opendistro-anomaly-detector plugin first with your package manager, before installing the upgraded opendistro-anomaly-detection (Support Docs).
