Abstract: Embodiments of the present disclosure may provide a data protection system that performs identification of errors from queries on a database. The data protection system can further identify corrupted data from additional errors, are difficult to detect, and occur between layers of data in the database system. The data protection system can perform corrections of the error data by rebuilding database data or removing the corrupted data.

Abstract: Techniques described herein can allow users to share cached results of an original query with other users while protecting sensitive information. The techniques described herein can check whether the other users have access to the underlying data queried before allowing those users to see the stored query results. That is, the system may perform privilege checks on the shared users before giving them access to the stored query results but without having to re-run the original query.

Abstract: The subject technology selects a most recently created file from a set of files stored in a source table. The subject technology iterates, in the source table, starting from the most recently created file up to an age threshold to select a first set of files for performing a first defragmentation process. The subject technology sets an indication corresponding to a particular file that is a last file, from the first set of files, that meets the age threshold. The subject technology performs the first defragmentation process on the selected first set of files. The subject technology determines that the first defragmentation process was successful.
