AWS OpenSearch Support
AWS OpenSearch support, troubleshooting and optimization.
OpenSearch clusters fail in predictable ways: too many shards, JVM memory pressure, full disks and mis-sized nodes.
Common OpenSearch problems we fix
The Amazon OpenSearch Service issues our engineers see most often, and how we resolve them.
OpenSearch cluster status red or yellow
Red means primary shards are missing, and yellow means replicas are unassigned, often from disk watermarks or node loss. We diagnose allocation and restore health.
OpenSearch high JVM memory pressure
Too many shards, large fielddata and heavy aggregations strain the heap. We reduce shard counts, tune mappings and scale nodes.
OpenSearch disk full and index lifecycle
Indices that never expire fill storage. We add Index State Management for rollover, warm tiers and deletion.
OpenSearch slow search and indexing
Bad mappings, refresh settings and bulk sizing hurt performance. We tune them and size the cluster.
OpenSearch access and VPC problems
Fine-grained access control and VPC domains make connectivity tricky. We fix policies and networking.

Frequently Asked Questions
Why is my OpenSearch cluster red?
A primary shard is unassigned, often due to a failed node or low disk. We find the cause and recover it.
How many shards should I use?
Fewer, larger shards are usually better. Aim for shards in the tens of gigabytes rather than thousands of tiny ones.
Can you reduce OpenSearch cost?
Yes, with right-sizing, UltraWarm and cold storage tiers and lifecycle policies.
