Each snapshot chunk includes a number of deduplication chunks. Each deduplication chunk is mapped to a disk chunk on a disk. The method includes creating a snapshot of the live volume and, for each host write to a snapshot chunk of the live volume that shares a set of disk chunks with a snapshot, performing a snapshot copy-on-write operation by a using a deduplication operation.

Abstract: Machine learning of selections of electronic records between a user environment and a customer environment is implemented using an intermediary virtual environment. A request received from the user environment includes a request for electronic records corresponding to the customer environment. A selection of electronic records is determined based on the request and transmitted to the user environment. A message received from the user environment includes an indication of one or more electronic records selected from the user environment. A next request from the customer environment includes a request to determine that a second selection of electronic records of the customer environment is indicated within the intermediary virtual environment. A message is transmitted to the customer environment responsive to determining that the second selection of electronic records corresponds to the one or more electronic records indicated from the user environment.

Abstract: Distributed database management systems may perform range queries over the leading portion of a primary key. Non-random distribution of data may improve performance related to the processing of range queries, but may tend to cause workload to be concentrated on particular partitions. Groups of partitions may be expanded and collapsed based on detection of disproportionate workload. Disproportionate write workload may be distributed among a group of partitions that can subsequently be queried using a federated approach. Disproportionate read workload may be distributed among a group of read-only replicated partitions.

Abstract: Database performance may be improved by creating additional backups from an existing backup, rather than the original database or audit log source. A second backup may be created from a first backup by copying the files from the first backup to the second backup. The replication from a first backup to a second backup with modification of the file history information allows identical backups to exist on different types of storage devices, including virtual storage devices. Continue functionality may be implemented during a move function to restart replication at a new starting point while retaining the existing move set. Tape-type-override functionality may be implemented during the replication to replace the tape type for the backups with another compatible type while retaining the original type for history file entries, tape trailers, and messages.

Abstract: Virtualization sprawl can lead to virtual machines with no designated periodic backup. If the data associated with these unprotected virtual machines is not backed up, it cannot be restored if needed, leading to system failures. A data storage system identifies and protects the unprotected virtual machines. For instance, the system compares a list of virtual machines with a list of computing devices having a designated backup policy in the data storage system and determines which of the virtual machines are unprotected. The system further automatically categorizes the unprotected virtual machines, identifies those unprotected virtual machines that remain uncategorized, and applies a default backup policy to the uncategorized and unprotected virtual machines to provide protected virtual machines.

The approach operates by calculating weights that correspond to search terms included in the plurality of words. The search terms include the plurality of words and may include terms that are one or more sequences of adjacent words included in the question. Based on the calculated weights and the words in the question, the approach generates a query that is used to search a corpus that is managed by the QA system with the search resulting in one or more search results.

Abstract: Non-blocking processing of federated transactions may be implemented for distributed data partitions. A transaction may be received that specifies keys at data nodes to lock in order to perform the transaction. Lock requests are generated and sent to the data nodes which identify sibling keys to be locked at other data nodes for the transaction. In response to receiving the lock requests, data nodes may send to lock queues indicating other lock requests for the keys at the data node. An evaluation of the lock queues based, at least in part, on an ordering of the lock requests in the lock queues may be performed to identify a particular transaction to commit. Once identified, a request to commit the identified transaction may be sent to the particular data nodes indicated by the sibling keys in a lock request for the identified transaction.

Abstract: A stream application receives a stream of tuples to be processed by a plurality of processing elements. The plurality of processing elements operate on one or more compute nodes. Each processing element has one or more stream operators. Segments of software code are embedded in a tuple of the stream of tuples. The tuple retrieves one or more compute node metrics. The compute node metrics describe one or more resources of a first compute node. The tuple obtains tuple information of one or more tuples of the stream of tuples to be processed by a first stream operator that operates on the one or more resources. The tuple determines a prospective resource disparity related to the first stream operator based on the obtained tuple information and the compute node metrics. The tuple transmits a resource request to the stream application based on the determined prospective resource disparity.

Abstract: In one example, a method for managing data includes detecting, in a shared multi-tenant deduplication system, a data stream that is specific to a particular user and that includes one or more user objects each having one or more data chunks. The data associated with the user is salted by associating a user-specific salt with the data chunks of the one or more user objects to form user-specific combinations of the form ((user-specific salt)+(user data chunk)). Finally, the user data is processed using the user-specific salt.

Abstract: Embodiments provide a migration instruction that effectuates the migration of a pluggable database from a source database server instance to a destination database server instance. Upon receiving the migration instruction, the migrating pluggable database is opened at the destination instance. Connections are terminated at the source instance at a rate that is determined based on statistics maintained for one or more of: the migrating pluggable database, the source instance, the destination instance, a container database, etc. Furthermore, once the migration instruction is received, a certain amount of time is provided before the source instance flushes the dirty buffers for the migrating pluggable database from the buffer cache of the source instance. The delay in flushing dirty buffers from buffer cache allows the source instance to provide data blocks, of the migrating pluggable database, directly to the destination database server instance from the cache.
