When using Server datasources Alteryx can take a long time to query metadata, particularly for long complex queries. This often happens on opening a module or clicking on the Input tool to eit properties.
This leads to frustration with these modules. It would be good for Alteryx to cache the metadata (i.e. columns) from these inputs and prompt the user to reuse this cached data if it it takes longer than say 2 seconds to retrieve the query.
