Abstract: Batch processing of undo log records may be performed for rolling back a database transaction. When a rollback operation for a database transaction is performed, undo log records from an undo log to rollback the database transaction are divided into different groups of undo log records. Different requests for the different undo log records are sent to a storage system to be performed. If a conflict is detected for an undo log record in a group, an indication of the conflicting undo log record may be provided to indicate the conflict. The group of undo log records may be resent with a request to reapply the undo log records in the group. When all groups have been identified as successfully completed, then the rollback operation may be considered completed.

Abstract: Techniques for handling highly amortized metadata page updates in storage clusters with delta log-based architectures. In response to performance of a transaction commit operation, bulk metadata pages are written in a transactional area of persistent memory in association with a unique transaction identifier. Further, raw delta updates to metadata pages and, for each bulk metadata page, a specialized flag, are written to a metadata delta log in association with the unique transaction ID. The specialized flag provides an indication that all delta updates that have occurred previous to the writing of a bulk metadata page are no longer relevant and should be dropped. The raw delta updates to metadata pages and specialized flags are updated in a volatile memory structure. The bulk metadata pages are flushed from the transactional buffer area directly to a metadata store of a storage array in a manner that bypasses the metadata delta log.

Abstract: An exemplary point-of-interest merging system accesses point-of-interest data records. Each point-of-interest data record includes data representative of a distinct set of features for a distinct point-of-interest. The merging system generates, based on the distinct sets of features of the point-of-interest data records, a graph data structure that includes the point-of-interest data records and weighted feature relationships interconnecting the point-of-interest data records. The merging system clusters, based on the graph data structure, the point-of-interest data records into subset groups of point-of-interest data records. The merging system generates one or more merged point-of-interest data records based on the clustered subset groups of point-of-interest data records.

Abstract: A multi-version database includes user-defined blockchain containers, where each of the user-defined blockchain containers is configured based on a type of data to be stored in a corresponding user-defined blockchain container. Each of the user-defined blockchain containers includes a set of one or more fields defined by a user. A command to write data to the multi-version database is received, where the command includes an identification of a first blockchain container of the user-defined blockchain containers, an identification of at least one of the set of one or more fields of the first blockchain container, and a value to write for at least one field of the set of one or more fields. A record is generated for the first blockchain container, the record including the value to write for the at least one field. A current state of the first blockchain container is then updated to include the record.
