摘要： The present teaching relates to concurrency control in log-structured merge (LSM) data stores. In one example, a call is received from a thread for writing a value to a key of LSM components. A shared mode lock is set on the LSM components in response to the call. The value is written to the key once the shared mode lock is set on the LSM components. The shared mode lock is released from the LSM components after the value is written to the key.
摘要翻译：本教程涉及日志结构合并（LSM）数据存储中的并发控制。在一个示例中，从用于将值写入LSM组件的键的线程接收到呼叫。响应于该呼叫，在LSM组件上设置共享模式锁定。一旦在LSM组件上设置了共享模式锁定，该值将被写入密钥。将值写入密钥后，共享模式锁将从LSM组件释放。

摘要： In one embodiment, a set of lock and unlock instructions in a read phase of a computer-readable program is replaced with a first set of tracking instructions, wherein the first set of tracking instructions track a set of locked objects identifying objects that would have been locked by executing the set of lock and unlock instructions. A second set of tracking instructions is inserted into the read phase of the computer-readable program, wherein the second set of tracking instructions track a set of read objects indicating versions of objects that are read. Validation instructions are inserted into the computer-readable program, wherein the validation instructions validate that the versions of objects in the set of read objects have not changed since they were last read and lock the set of locked objects that would have been locked upon completing execution of the set of lock and unlock instructions. Update instructions are added to an update phase of the computer-readable program, where the update instructions increment a current version of an object each time a value of the object is updated or a lock of the object is released.
摘要翻译：在一个实施例中，计算机可读程序的读取阶段中的一组锁定和解锁指令被替换为第一组跟踪指令，其中第一组跟踪指令跟踪一组锁定对象，该对锁定对象标识将被通过执行锁定和解锁指令来锁定。第二组跟踪指令被插入到计算机可读程序的读取阶段，其中第二组跟踪指令跟踪一组读取对象，指示所读取的对象的版本。验证指令被插入到计算机可读程序中，其中验证指令验证读取对象集合中的对象的版本自上次读取以来没有改变，并且锁定在完成执行时被锁定的一组锁定对象的锁定和解锁指令集。更新指令被添加到计算机可读程序的更新阶段，其中更新指令在对象的值被更新或对象的锁释放时递增对象的当前版本。

摘要： Disclosed herein is an enhanced device personalization that personalizes a user's experience with a device, e.g., a multi-user device. Rather than personalizing based on the specific user(s) that are using, an active entity, which represents a type of consumption, may be generated and used to make recommendations for personalizing an experience using the device. In a case of a multi-user device, each user's experience is personalized by determining an active entity for the user's experience and without knowledge of which user is using the device.

摘要： Techniques are provided for detecting and resolving conflicts between native and transactional applications sharing a common database. As transactions are received at the database system, a timestamp is assigned to both the start and the commit time of a transaction, where the timestamps are synchronized with a logical clock in the database system. When the database system receives a native operation, the database system increments the time in the logical clock and assigns that updated time to the native operation. When the transaction is ready to commit, database system may determine conflicts between native and transactional operations. If the database system determines that a native operation conflicts with a transactional operation, database system will abort the transaction.
摘要翻译：提供了技术来检测和解决共享公共数据库的本机和事务应用程序之间的冲突。当数据库系统接收到事务时，时间戳被分配给事务的开始和提交时间，其中时间戳与数据库系统中的逻辑时钟同步。当数据库系统接收到本地操作时，数据库系统会在逻辑时钟中增加时间，并将更新的时间分配给本机操作。当事务准备提交时，数据库系统可能会确定本机和事务操作之间的冲突。如果数据库系统确定本机操作与事务操作冲突，则数据库系统将中止该事务。
