摘要： The efficient use of threads that issue calls to log events. While waiting for the call to return or complete, the threads are put to work on other tasks that are not part of the process that generated the event. This can occur without context switching of the thread, especially when the task to be performed is state-less or context free. In the efficient thread diversion process, the thread calls a logging component to log an event. This blocks the thread from continuing work on a process that the event is part of until the event is logged. The thread then performs a diversion task that is not part of the processing unit that the event is part of. After detecting that the event has logged, the thread continues work on the processing unit that the event is part of.
摘要翻译：
有效使用发出调用来记录事件的线程。在等待调用返回或完成时，线程将处理其他不属于生成事件的过程的任务的任务。这可以在线程没有上下文切换的情况下发生，特别是当要执行的任务是无状态或无上下文时。在高效的线程转换过程中，线程调用日志记录组件来记录事件。这会阻止线程继续处理该事件所属的进程，直到事件记录为止。该线程然后执行不属于该事件所属的处理单元的分流任务。在检测到事件已记录后，线程将继续处理该事件所属的处理单元。

摘要： Data base performance is improved using write-behind optimization of covering cache. Non-volatile memory data cache includes a full copy of stored data file(s). Data cache and storage writes, checkpoints, and recovery may be decoupled (e.g., with separate writes, checkpoints and recoveries). A covering data cache supports improved performance by supporting database operation during storage delays or outages and/or by supporting reduced I/O operations using aggregate writes of contiguous data pages (e.g., clean and dirty pages) to stored data file(s). Aggregate writes reduce data file fragmentation and reduce the cost of snapshots. Performing write-behind operations in a background process with optimistic concurrency control may support improved database performance, for example, by not interfering with write operations to data cache. Data cache may store (e.g., in metadata) data cache checkpoint information and storage checkpoint information. A stored data file may store storage checkpoint information (e.g., in a file header).

摘要： Embodiments described herein detect data corruption in a distributed data set system. For example, a system comprises node(s) for processing queries with respect to a distributed data set comprising a plurality of storage segments. A write transaction resulting from a query with respect to a particular storage segment is logged in a log record that describes a modification to the storage segment. A log service provides the log record to a data server managing a portion of the distributed data set in which the storage segment is included, which performs the write transaction with respect to the storage segment. For redundancy purposes, the data server has replica(s) that manage respective replicas of the portion of the distributed data set managed thereby. For backup purposes, snapshots of the replica(s) are periodically generated. To determine a data corruption, a snapshot of one replica is cross-validated with a snapshot of another replica.

摘要： Assembly of a state of user data as of a particular point in time in the context of the data being spread across multiple storage segment servers. Furthermore, the assembly occurs despite the storage segment servers not needing to coordinate a timing of any snapshots. Rather, the storage segment servers perform a snapshot of the portion of the data that it individually stores without having to coordinate with any other storage segment server. The particular point of time may be any arbitrary time, such as a time selected by a user.

摘要： Distributed database systems including compute nodes and page servers are described herein that enable separating logical and physical storage of database files in a distributed database system. A distributed database system includes a page server and a compute node and is configured to store a logical database file that includes data and is associated with a file identifier. Each page server is configurable to store slices (i.e., subportions) of the logical database file. The compute node is coupled to the plurality of page servers and configured to store the logical database file responsive to a received command. In an aspect, such storage may comprise slicing the data comprising the logical database file into a set of slices with each being associated with a respective page server, maintaining an endpoint mapping for each slice of the first set of slices, and transmitting each slice to the associated for storage thereby.

摘要： Caching storage segments (e.g., pages) loaded from a remote storage such that, during recovery, the cached loaded storage segments may be at least partially recovered without reloading the storage segments from the remote storage. During normal operation of a computing system, storage segments are loaded from remote storage into local memory of a computing system. At some point, either due to eviction of the storage segment due to aging out of the storage segment, or due to writing of the storage segment, it is determined to write at least some of the loaded storage segments into local persistent storage. In conjunction with this, the corresponding storage segment is written to a respective storage address of the local persistent storage. Also, a correlation between an identifier of the storage segment and the respective address in the persistent storage is recorded in a persistent data structure.

摘要： The use of log marking (otherwise known as "coloring") of sub-portions of a log that records actions (e.g., data operations) performed by a computing system. The log is composed of multiple sub-portions, such as virtual log files, which are successively added to the log as the log grows. For instance, the sub-portions may be virtual log files of the log. The principles described herein change the use of log marking depending on which sub-portion of the log is being marked. If the computing system fails, and recovery is needed, the recovery process can thus deterministically identify where the last written log record is.

摘要： The bifurcation of a log into a fixed-size log portion and a growable log portion. Log records are first written to the fixed-size log portion. At some point, the older log records within the fixed-size log portion are destaged to the growable log portion. Destaging may involve copying the log records from the fixed-size log portion and tacking the log record onto the end of the growable log portion. This destaging might occur one sub-portion (e.g., one virtual log file) at a time. The more recent log records are within the fixed-size log portion. Accordingly, new writes to the log occur to the fixed-size log portion. Furthermore, a large portion of the reads are of the more recent log records within the fixed-size log portion. Thus, optimizing performance within the fixed-size log portion results in significant improvement in the performance of the overall log.

摘要： A storage segment server environment that includes storage segment server(s) that cover a contiguous address space of data. The storage segment server has storage segments that are contiguous and that matches the address space of a respective of storage segments in the cloud store service. Thus, a read of the contiguous address spaces of the data from the cloud store service may instead be handled as a single read of the contiguous address space of the storage segment server. Each storage segment server(s) may be assigned to a range within the total contiguous address space of the data. Each storage segment server(s) includes a respective storage segment write component that is configured to perform write operations to storage segments in the respective storage segment server. Each storage segment server(s) also includes a respective cloud storage write component that initiates corresponding write operations to the cloud store service.
