Abstract: A composition and use thereof. The composition comprises an active component a and an active component b; the active component a is a compound as shown in general formula A; and the active component b is at least one of compounds which have insecticidal, acaricidal or bactericidal activity and are different from the compound as shown in general formula A. The composition has the advantages of synergistic effect and expanding prevention and treatment spectrum, and can be used for preventing and treating various pests, particularly mite damage, and plant diseases caused by various fungi, bacteria, nematodes and viruses.

Abstract: Techniques perform log management. Such techniques involve obtaining a count value of a counter associated with a log entry in the log, the count value of the counter incrementing at a predetermined frequency. Such techniques further involve determining a rough time instant when the log entry is created based on the count value, a reference count value of the counter associated with the log entry, a reference time corresponding to the reference count value and the frequency. Such techniques further involve correcting the rough time instant based at least in part on the frequency and a set of count values of the counter corresponding to a set of time instants, to determine a corrected time when the log entry is created. Accordingly, the log backed up to the external storage device has accurate time information.

Abstract: A method, computer program product, and computer system for identifying, by a computing device, historical block usage in a plurality of slices for a user. At least a portion of the plurality of slices to keep during an evacuation process for the plurality of slices may be determined. At least the portion of the plurality of slices may be excluded from the evacuation process for the plurality of slices based upon, at least in part, the historical block usage in the plurality of slices for the user.

Abstract: Disclosed herein is an apparatus and method for a naming service in a distributed memory object system. In one embodiment, a name service method includes electing a primary node for the master key value store from a plurality of name service nodes, the primary node to receive master key value requests, a master key value store containing an entry for each directory within the distributed memory object, wherein the master key value store is configured for associating a directory pathname to a uniform unique identifier, and replicating the master key value store across the plurality of name service nodes.

Abstract: Disclosed herein is an apparatus and method for a key value store snapshot for a distributed memory object system.

Abstract: The current disclosure is directed towards providing methods and systems enabling a plurality of key-value stores to be persisted within a single direct access memory space comprising persistent memory, and further enabling a single key-value store to be implemented via a plurality of memory spaces. In one embodiment, a method comprising: creating a first create-key-value-store operation-performed entry in a global log persisted within a first memory space; allocating a first key-value store name and a first key-value store root address within a second memory space; persisting the first key-value store name and the first key-value store root address within a first local log of the second memory space; updating the global log of the first memory space to include the first key-value store name and the first key-value store root address; and adding the first key-value store name and the first key-value store root address to a meta key-value store.

Abstract: Techniques for issuing a data storage management request may include: receiving, from a client at a data storage system, a set of one or more messages; performing natural language processing on the set of one or more messages to extract first information used in forming the data storage management request; executing the data storage management request in accordance with the first information extracted; and responsive to executing the request, sending a response to the client indicating a result of executing the data storage management request. State information may be retained in connection with a first conversation to obtain information for a first request or command. If the first conversation is interrupted to commence a second conversation for a second request, the state information may be stored for the duration of the second conversation and then restored to resume the first conversation from the point of interruption.
