Abstract: Techniques for creating and using error tables to track errors associated with a base table are described. A command to perform an operation on a base table stored in a network-based data system can be received and executed, causing at least one error. At least one error record corresponding to the at least one error can be inputted into an error table, which is nested with the base table. Contextual information can be added to the at least one error record.

Abstract: A data transfer request can be received by each of multiple deployments; however, only a primary deployment can process the request. The data transferred by the primary deployment may be replicated in the secondary deployments. In response to a failover event, one of the secondary deployments can be designated as the new primary development and continue the data transfer based on the data transfer request and the replication information received from the old primary deployment prior to the failover.

Abstract: A data platform including an error handling framework for loading of input data. The data platform generates input data columns based on an input file and generates result data columns based on the input data columns and evaluating expressions. The data platform detects projection errors during the generating of the result data columns and stores result error indicators in error indicator arrays of the result data columns based on the projection errors. The data platform generates filtered result data columns based on the result data columns and the result error indicator arrays of the result data columns and stores the filtered result data columns in a database of the data platform.
