Monstache is a Go daemon that continuously syncs MongoDB collections into Elasticsearch (or OpenSearch) in realtime using change streams. It enables full-text search, aggregations, and Kibana dashboards over MongoDB data.

Use cases

• keep elasticsearch index in sync with mongodb in realtime
• add full-text search to a mongodb application
• build kibana dashboards over mongodb data
• run a one-time full sync of mongodb collections to elasticsearch
• transform or filter documents before indexing into elasticsearch
• track document changes over time for auditing

When to choose

• you use MongoDB as your primary store and need Elasticsearch for search or analytics
• you want a single lightweight binary with change-stream-based realtime sync
• you need HA clustering, resume, or sharded-cluster support out of the box

When to avoid

• you don't use MongoDB or Elasticsearch/OpenSearch
• you need a sync tool with a GUI or managed cloud service
• you need custom logic beyond what Go plugins or JavaScript transforms provide
