Abstract: In an embodiment, before modifying a persistent ORL (ORL), a database management system (DBMS) persists redo for a transaction and acknowledges that the transaction is committed. Later, the redo is appended onto the ORL. The DBMS stores first redo for a first transaction into a first PRB and second redo for a second transaction into a second PRB. Later, both redo are appended onto an ORL. The DBMS stores redo of first transactions in volatile SRBs (SLBs) respectively of database sessions. That redo is stored in a volatile shared buffer that is shared by the database sessions. Redo of second transactions is stored in the volatile shared buffer, but not in the SLBs. During re-silvering and recovery, the DBMS retrieves redo from fast persistent storage and then appends the redo onto an ORL in slow persistent storage. After re-silvering, during recovery, the redo from the ORL is applied to a persistent database block.

Abstract: Embodiments enforce user access rights to a data view, by initially generating a replication table of the view. The replication table may include all view data to which any user is entitled. This replication table may be generated during a first database session having a first value for a session variable. Next, a data access control structure is applied to the replication table to produce output comprising a subset of the view data for a specific user. This output may be produced during a second database session having a second value for the session variable. By initially generating the view replication table up front, processing resources are conserved in later stages when access control structures are applied to grant view access rights to particular users. Alternative embodiments may implement access control to data views, through the creation and storage of derived views.

Abstract: A data management system (DMS) may receive entries corresponding to files and directories of a storage system that changed within a time period. The received entries may include metadata associated with the changed files and directories. The DMS may identify one or more directories that were renamed or deleted within the time period by analyzing the metadata from the received entries. The DMS may identify descendent directories and descendent files corresponding to the one or more renamed or deleted directories. The DMS may update path identifiers associated with the descendent directories and the descendent files based on the metadata from the received entries. The DMS may generate an updated index file based on updating the path identifiers for the descendent directories and the descendent files. The described techniques may enable the DMS to identify renames and deletions with greater efficiency, among other benefits.

Abstract: Techniques are provided for implementing a defragmentation process during a merge operation performed by a re-compaction process upon a log structured merge tree. The log structured merge tree is used to store keys of key-value pairs within a key-value store. As the log structured merge tree fills with keys over time, the re-compaction process is performed to merge keys down to lower levels of the log structured merge tree to re-compact the keys. Re-compaction can result in fragmentation because there is a lack of spatial locality of where the re-compaction operations re-writes the keys within storage. Fragmentation increases read and write amplification when accessing the keys stored in different locations within the storage. Accordingly, the defragmentation process is performed during a last merge operation of the re-compaction process in order to store keys together within the storage, thus reducing read and write amplification when accessing the keys.
