Type alias WriteStrategy

WriteStrategy: "merge" | "insertIfAbsent" | "insertDefaultIfAbsent"

Defines the various strategies available when inserting a document into a collection.

  • merge: the existing document will be merged with the document being inserted, if there is a pre-existing document.

  • insertIfAbsent: insert the document only if there is not already a document with the same ID in the store. If there is already a document in the store with the same ID then this will be a no-op.

  • insertDefaultIfAbsent: insert the document, with its contents treated as default data, only if there is not already a document with the same ID in the store. If there is already a document in the store with the same ID then this will be a no-op. Use this strategy if you want to insert default data for a given document ID, which you want to treat as common initial data amongst all peers and that you expect to be mutated or overwritten in due course.
