Introduction

Jaeger requires a persistent storage backend. Cassandra, Elasticsearch, and OpenSearch are the primary supported distributed storage backends. Additional backends are discussed here .

Please refer to Configuration page for details on configuring storage backends for Jaeger.

For large scale production deployment the Jaeger team recommends OpenSearch backend over Cassandra.

Remote Storage

Jaeger supports a gRPC-based [Remote Storage API][storage.proto] that allows extending the Jaeger ecosystem with custom storage backends, not directly supported by the project. These storage backends can be deployed as a remote gRPC server.

To use a remote storage as Jaeger storage backend, use grpc as the storage type and specify the remote gRPC server address. For more information, please refer to jaeger/plugin/storage/grpc .

Example config for remote storage can be found here .
