The following table identifies the recommended data-type mappings for Database Ingestion and Replication configurations with a MongoDB source and a Microsoft SQL Server target:
MongoDB Source Data Type
Microsoft SQL Server Target Data Type
document(2147483647)
varchar(max)
id(32)
char(128)
Note: For a MongoDB source, Database Ingestion and Replication creates two columns on the target: an ID column, which provides an identifier similar to a primary key, and a Document column, which contains a JSON object containing an entire MongoDB record. Therefore, the mappings show the target data type associated with each of these columns.
