Hot/warm data tiering for Aiven for OpenSearch®

Aiven for OpenSearch® now supports hot/warm data tiering on custom plans. This feature is in limited availability; contact Aiven to request access.

Clusters with tiered storage run two groups of data nodes: hot nodes on fast storage for active data, and warm nodes on larger, lower-cost storage for older data that is queried less often. Index State Management (ISM) policies automate the full lifecycle: new indexes land on hot nodes, roll over when they reach a size or age threshold, migrate to warm nodes after a retention period, and are optionally deleted.

Key details:

• Requires Aiven for OpenSearch® 2.19 or later.
• Configure index routing and ISM policies directly through the OpenSearch API or OpenSearch Dashboards.

For setup instructions and ISM policy examples, see Hot/warm data tiering in Aiven for OpenSearch®.
