Disclosed herein are system, method, and computer program product embodiments for managing timestamp information in memory systems. In an embodiment, an infrastructure may utilize a controller to manage sparse timestamp blocks. These sparse timestamp blocks may manage timestamp information in a persistent memory structure. Controller 110 may utilize a transient timestamp accessor to map the timestamp information for faster hash lookups. Controller 110 may also utilize a garbage collection map as a bitmap to further save processing steps. Controller 110 may utilize the sparse timestamp blocks, transient timestamp accessor, and garbage collection map to efficiently store timestamp data and to quickly retrieve the stored timestamp data.

Example storage systems, file system interfaces, and methods provide cache commit timing management for aggregated writes. A system includes a data cache configured to aggregate data requests in buffer segments. A cache manager determines a delay threshold for each buffer based on usage values of the data cache. The cache manager monitors a commit time value, determines when the commit time value satisfies the delay threshold, and moves aggregate data elements from the buffer to persistent storage.

A system and method comprising: receiving a request to write data stored at a first range of a first volume to a second range of a second volume, where first metadata for the first range of the first volume is associated with a range of physical addresses where the data is stored in the storage system; and responsive to receiving the request: creating second metadata for the second range of the second volume, wherein the second metadata is associated with the range of physical addresses where the data is stored in the storage system; and associating the second volume with the second metadata.

Techniques are disclosed to manage use of a global pool of memory comprising at least a portion of the runtime-managed heap. A request to reserve use of a portion of the global pool of memory is received from each of a plurality of transactions comprising a transactional workload of a database management system. A corresponding portion of the global pool of memory is allocated to each of at least a subset of the requesting transactions, to be used as a local pool of memory available to be used by the transaction to process the transaction.

A method for providing elastic columnar cache includes receiving cache configuration information indicating a maximum size and an incremental size for a cache associated with a user. The cache is configured to store a portion of a table in a row-major format. The method includes caching, in a column-major format, a subset of the plurality of columns of the table in the cache and receiving a plurality of data requests requesting access to the table and associated with a corresponding access pattern requiring access to one or more of the columns. While executing one or more workloads, the method includes, for each column of the table, determining an access frequency indicating a number of times the corresponding column is accessed over a predetermined time period and dynamically adjusting the subset of columns based on the access patterns, the maximum size, and the incremental size.

Delaying deletion of a dataset, including: associating an eradication timer with the dataset, wherein the eradication timer specifies an amount of time to delay a requested deletion of the dataset; determining that the amount of time to delay the requested deletion of the dataset should be modified; and modifying the eradication timer to specify a modified amount of time to delay the requested deletion of the dataset.

An information translation device, information translation method, and an information translation system based on Modbus are provided. The client module of the information translation device receives an information model file including identity information, receives a sensor signal corresponding to first identity information and Modbus data including memory addresses of Modbus protocol, determines a first memory address corresponding to the sensor signal according to sensed values of the sensor signal and values corresponding to each of the memory addresses and builds a memory address mapping table including the first memory address and the first identity information, and receives a first value of the first memory address and searches the first identity information corresponding to the first memory address according to the memory address mapping table. The server module of the information translation device receives the first value and the first identity information and transmits to an OPC UA device.

Techniques relating to caching a content object are disclosed. A first server receives a revalidation request, relating to a content object, from a requestor. It is determined that metadata, relating to the content object, is stored in a cache associated with the first server. In response, the first server determines not to retrieve the content object from a second server. The content object is not stored in the cache. A response to the revalidation request, indicating that the content object is not modified, is transmitted from the first server to the requestor, based on analyzing the metadata.

Described are methods, systems and computer readable media for providing a current row position query language construct and array processing query language constructs and associated processing.

A technique includes creating, by a computer, a sandboxed user account on the computer, where creating the sandboxed user account includes generating credentials for the sandboxed user account. The technique includes creating, by the computer, an operating system session and executing a single sign on (SSO) tool in the operating system session in association with the sandboxed user account. In response to a request that is associated with another user account to start up an application, authorizing, by the computer, use of the application by the other user account based on credentials that are associated with the other user account and starting up the application by the computer. Starting up the application includes using the SSO tool to inject SSO credentials for the other user account based on policy authorization into the application such that the application is executed in association with the sandboxed user account.
