Columns for Tables Not Visible in the Schema Tab
Issue
Columns for tables are not visible in the Schema tab.
Environment
Connector: MongoDB
Resolution
To resolve this issue, wait for the connection's initial sync to complete before going to the Schema tab.
Cause
MongoDB is a NoSQL database with no fixed columns and tables. Instead, it has collections (similar to tables) and dynamic schemas. It is a document-oriented database that uses JSON documents. During the connnection's initial sync, we examine the data and retrieve the column details. Therefore, this issue occurs when you attempt to view columns in the Schema tab before we complete the connection's initial sync.
