You can replicate Tables, Views, and Schemas. The available objects depend on your Azure Cosmos DB account permissions and configuration.

How often does Weld replicate data from Azure Cosmos DB?

Sync frequency depends on your Weld plan. Schedules range from every 5 minutes to daily intervals. Each sync processes only new and changed data.
