Don't use Elasticsearch or use it with caution if:
- You are looking for catering to transaction handling.
- You are planning to do a highly intensive computational job in the data store layer.
- You are looking to use this as a primary data store. If this is a requirement, when data is inserted, Elasticsearch has to re-index and this would take some time and wouldn't be available as and when the data was inserted and updated.
- You are looking for an ACID compliant data store.
- You are looking for a durable data store.
