摘要： Embodiments of the present invention provide for batch and incremental loading of data into a database. In the present invention, the loader infrastructure utilizes machine code database instructions and hardware acceleration to parallelize the load operations with the I/O operations. A large, hardware accelerator memory is used as staging cache for the load process. The load process also comprises an index profiling phase that enables balanced partitioning of the created indexes to allow for pipelined load. The online incremental loading process may also be performed while serving queries.

摘要： Techniques are provided for maintaining high propagation availability for non-persistent messages. Destination-to-instance mapping information is provided to a listener process for a cluster database. The destination-to-instance mapping indicates the current owner instance of each single-instance destination within the cluster database. To establish a connection to a single-instance destination, a sending process sends a connection request to the global listener. The connection request identifies the desired destination queue, but not the owner instance of the queue. The global listener for the cluster database uses the destination-to-instance mapping to determine which instance is the current owner of the specified queue, and establishes a connection between the sending process and the appropriate owner instance.
摘要翻译：提供了为非持久性消息保持高传播可用性的技术。将目标到实例的映射信息提供给集群数据库的侦听器进程。目标对实例映射指示集群数据库中每个单实例目标的当前所有者实例。要建立与单实例目标的连接，发送进程会向全局侦听器发送连接请求。连接请求标识所需的目标队列，但不标识队列的所有者实例。集群数据库的全局侦听器使用目标到实例映射来确定哪个实例是指定队列的当前所有者，并在发送进程和适当的所有者实例之间建立连接。

摘要： Embodiments of the present invention provide one or more hardware-friendly data structures that enable efficient hardware acceleration of database operations. In particular, the present invention employs a column-store format for the database. In the database, column-groups are stored with implicit row ids (RIDs) and a RID-to-primary key column having both column-store and row-store benefits via column hopping and a heap structure for adding new data. Fixed-width column compression allow for easy hardware database processing directly on the compressed data. A global database virtual address space is utilized that allows for arithmetic derivation of any physical address of the data regardless of its location. A word compression dictionary with token compare and sort index is also provided to allow for efficient hardware-based searching of text. A tuple reconstruction process is provided as well that allows hardware to reconstruct a row by stitching together data from multiple column groups.

摘要： An approach for reducing transport of messages between nodes of a multi-node system is presented wherein a message queue is associated with a queue service, and based on which node the message queue resides, one of the nodes is registered as hosting the associated queue service. In response to a client attempting to connect and requesting a particular queue service, the client is caused to connect to the node on which the queue service resides.

摘要： Embodiments of the present invention provide fine grain concurrency control for transactions in the presence of database updates. During operations, each transaction is assigned a snapshot version number or SVN. A SVN refers to a historical snapshot of the database that can be created periodically or on demand. Transactions are thus tied to a particular SVN, such as, when the transaction was created. Queries belonging to the transactions can access data that is consistent as of a point in time, for example, corresponding to the latest SVN when the transaction was created. At various times, data from the database stored in a memory can be updated using the snapshot data corresponding to a SVN. When a transaction is committed, a snapshot of the database with a new SVN is created based on the data modified by the transaction and the snapshot is synchronized to the memory. When a transaction query requires data from a version of the database corresponding to a SVN, the data in the memory may be synchronized with the snapshot data corresponding to that SVN.
摘要翻译：在存在数据库更新的情况下，本发明的实施例为事务提供细粒度并行性控制。在操作期间，为每个事务分配一个快照版本号或SVN。 SVN是指可以定期或按需创建的数据库的历史快照。因此，事务与特定的SVN相关联，例如，当事务被创建时。属于事务的查询可以访问一个时间点一致的数据，例如对应于创建事务时的最新SVN。在不同时间，可以使用对应于SVN的快照数据来更新存储在存储器中的数据库的数据。提交事务时，将根据事务修改的数据创建具有新SVN的数据库快照，并将快照与内存同步。当事务查询需要来自与SVN对应的数据库的版本的数据时，存储器中的数据可以与对应于该SVN的快照数据同步。

摘要： A method and apparatus for propagating and managing data, transactions and events either within a database, or from one database to another is provided. In one embodiment, messages are propagated from a source to a first queue and a second queue with the queues associated with the same database. The connection from the source to each queue maintains its own propagation job. This method could also be employed with cluster databases.
