摘要： A multi-version removal manager for a transaction processing system is disclosed. A visibility sequence number is provided to versions such that operations with a lower sequence number than the visibility sequence number have been applied and a preselected amount of operations with a higher sequence number could have been applied. Visible version versions are maintained and versions related to a visibility sequence number are removed after an executing transaction is disposed.

摘要： In one embodiment, a method of performing point-in-time recovery (PITR) in a massively parallel processing (MPP) database includes receiving, by a data node from a coordinator, a PITR recovery request and reading a log record of the MPP database. The method also includes determining a type of the log record and updating a transaction table when the type of the log record is an abort transaction or a commit transaction.

摘要： Embodiments of the present invention provide a data storage method and apparatus for a distributed database. The method includes: receiving, by a first node, a record insertion request, where the record insertion request carries a first record; determining, by the first node according to a mapping relationship between a foreign key identifier and a storage node, a first storage node on which a first associated record that corresponds to the first record is located, where a primary key identifier of the first associated record is the same as a foreign key identifier of the first record; and inserting, by the first node, the first record to a second node in the first storage nodes. The method provided in the embodiments of the present invention resolves a technical problem of low data insertion efficiency and a low data update speed in the prior art.

摘要： A process for handling interleaved sequences using RNNs includes receiving data of a first transaction, retrieving a first state (e.g., a default or a saved RNN state for an entity associated with the first transaction), and determining a new second state and a prediction result using the first state and an input data based on the first transaction. The process includes updating the saved RNN state for the entity to be the second state. The process includes receiving data of a second transaction, where the second transaction is associated with the same entity as the first transaction. The process unloops an RNN associated with the saved RNN state including by: retrieving the second state, determining a new third state and a prediction result using the second state and an input data based the second transaction, and updating the saved RNN state for the entity to be the third state.

摘要： A transaction processing protocol for serverless database management systems can use a transaction scheduler to guarantee consistent serializable execution though analysis of the access pattern of transaction types and appropriate ordering of the transaction's events at runtime. A transaction topology is determined for each type of transaction and these are combined and used to generate a serialization graph. Cycles in the serialization graph are identified and breaking transaction types which may break the cycles are determined. When transaction requests are received, a breaking type of transaction is scheduled as a last transaction in the current epoch and later transactions not having the breaking transaction type are scheduled to execute in the next epoch.

摘要： A computer for executing processing through use of a database, the computer comprising: a processor including a cache memory; and a non-volatile memory coupled to the processor, the non-volatile memory having the database constructed thereon. The computer comprises: a database management module configured to execute processing on the database; and a write processing module configured to write data stored in the cache memory into the database. The write processing module writes data that is operated in the transaction processing into the database among data stored in the cache memory, in a case of receiving a commit request for transaction processing that uses the database.
