Hello. I am mapping data from Electronic Clinical Works (eCW) to Medplum server. in eCW there are data structures that are collections of . Some of those collections have more than 100K entries. A consuming web application need to fetch an object by id. What is the best way to store such a massive amount of data in Medplum. What FHIR resources should be used for this task?

Batch https://www.medplum.com/docs/fhir-datastore/fhir-batch-requests seems appropriate, though there are limits

Thank you for the reply. How do I search for a resource inside a list of Bundles without loading all the bundles and search in each?
