   This happens because of Netty used by CosmsoDB SDK is configured to use max 2 MB for response body size. So if we query for say 200 docs and each doc is 1 MB in size then dependeing on how many returns are returned from a given partition it can exceed the default limit of 2 MB. This can now be changed by setting system property `MAX_HTTP_BODY_LENGTH_IN_BYTES` to higher value. 
   
   As a proper fix we can add retry logic in CosmosDBArtifactStore query impl by checking for this error and then retry with a lesser number of item to fetch per individual batch
