摘要： A system, method and computer product for managing distributed transactions of a database. A transaction manager is provided for each of a plurality of transactions of the database. Each transaction manager is configured to perform functions that include generating a transaction token that specifies data to be visible for a transaction on the database. The database contains both row and column storage engines, and the transaction token includes a transaction identifier (TID) for identifying committed transactions and uncommitted transactions. A last computed transaction is designated with a computed identifier (CID), record-level locking of records of the database is performed using the TID and CID to execute the transaction, and the plurality of transactions of the database are executed with each transaction manager.

摘要： Methods and apparatus, including computer program products, for selection of rows and values from indexes with updates. In general, rows of an index may be associated with validity flags that indicate whether a row has been updated with an update inserted in a delta index; one scheme for value identifiers may be used for an index and another scheme for one or more delta indexes where all of the indexes are, to at least some extent, compressed according to dictionary-based compression; and multiple delta indexes may be used in alternation such that one delta index may accept updates while another is being updated. The delta indexes may also have validity flags and all updates, such as modifications of values, deletion of records, and inserting of new records may be handled as updates accepted by one or more delta indexes.
摘要翻译：方法和设备，包括计算机程序产品，用于从具有更新的索引中选择行和值。通常，索引的行可以与指示是否已经用插入在delta索引中的更新来更新行的有效性标志相关联; 价值标识符的一个方案可以用于索引，另一个方案用于一个或多个增量索引，其中所有索引至少在一定程度上根据基于字典的压缩被压缩; 并且可以交替地使用多个增量索引，使得一个增量索引可以接受更新，而另一个增量索引正在被更新。增量索引还可以具有有效性标志，并且可以将所有更新（例如值的修改，记录的删除和插入新记录）处理为由一个或多个增量索引接受的更新。

摘要： According to some embodiments, a column-oriented in-memory database structure may be established. The database structure may, for example, include a main store and a dictionary compressed delta store. Moreover, the delta store may comprise a value identifier vector and a delta dictionary associated with a column of the database. A transaction associated with the column may then be received and recorded within the delta store. According to some embodiments, entries associated with the transaction may be added to a value log of the value identifier vector and, independently, to a dictionary log of the delta dictionary.

摘要： A system is described for processing schema updated in a zero-downtime environment. A technique includes establishing an application session to access a database, receiving a schema update, converting the database to an updated database according to the schema update after establishing the application session, generating a temporary compensation view from the schema update, the temporary compensation view containing compensation logic to locate database objects belonging to the database, receiving a database transaction from the application session to access a database object in the database; and processing the compensation logic to locate the database object.

摘要： A system, method and computer product for accelerating parallel database transactions. One or more data processors execute a first transaction on a database. The first transaction includes a transactional lock associated with each of one or more records to update the one or more records during the first transaction, and a pre-commit command to request acknowledgement of committing the updating of the one or more records during the first transaction. The one or more data processors execute a second transaction on the database in parallel with the first transaction. The second transaction includes a transactional lock associated with each of one or more records to update the one or more records during the second transaction, and a pre-commit command to request acknowledgement of committing the updating of the one or more records during the second transaction. The transactional locks of the first and second transactions are released before flushing log records associated with the first and second transactions.

摘要： Local dependency metadata can be collected from local metadata repositories of a plurality of development systems in a layered development system landscape, and a global where-used list that includes intra-layer and inter-layer dependencies between development entities in a layered development system landscape can be created, for example by aggregating the collected local dependency data. A usage metric quantifying how frequently each development entity is depended upon by other development entities in the layered development system landscape can be assigned to each development entity in the layered development system landscape. A measure of a relative effect of a change to one of the development entities on other development entities in the layered development system landscape can be promoted.
