摘要： The subject matter disclosed herein provides methods for the forced ordering of a dictionary based on row identifier values. A plurality of concurrent transactions can be handled in an in-memory database. At least one of the transactions can include at least one write operation to a dictionary. Each write operation can be assigned a row identifier (ID). At least one of the write operations can be written to the dictionary out of sequence. The sequence can be based on the row ID. Each row ID in the dictionary can be mapped to a corresponding value identifier in the dictionary. The dictionary can position the value identifiers so that the corresponding row IDs are in a sorted sequential order based on the row ID. Related apparatus, systems, techniques, and articles are also described.

摘要翻译：本文公开的主题提供了基于行标识符值强制排序字典的方法。可以在内存数据库中处理多个并发事务。至少一个事务可以包括对字典的至少一个写入操作。每个写操作都可以被分配一个行标识符（ID）。写入操作中的至少一个可以按顺序写入字典。该序列可以基于行ID。字典中的每个行ID都可以映射到字典中的相应值标识符。字典可以定位值标识符，使得相应的行ID基于行ID按照排序的顺序排列。还描述了相关装置，系统，技术和制品。

摘要： A method, computer program product and system are provided. The method, computer program product and system execute a process for determining a size of an object, the object having raw data that is operable upon by one or more physical operators. If the object is smaller than a threshold size, the object is stored in main memory of an in-memory database system. If the object is equal to or larger than the threshold size, the object is stored in a persistency of a disk storage, where storing the object in a disk storage further includes generating a global container identifier (ID) for the object, the global container ID referencing raw data of the object stored in the persistency of the disk storage.
摘要翻译：提供了一种方法，计算机程序产品和系统。所述方法，计算机程序产品和系统执行用于确定对象的大小的过程，所述对象具有可由一个或多个物理操作者操作的原始数据。如果对象小于阈值大小，则对象存储在内存数据库系统的主存储器中。如果对象等于或大于阈值大小，则对象被存储在磁盘存储器的持久性中，其中将对象存储在磁盘存储器中还包括为对象生成全局容器标识符（ID），全局容器 ID引用存储在磁盘存储器的持久性中的对象的原始数据。

摘要： Data replication in a database includes identifying a source database system. The source database includes a main index file and a delta log file. To create a replica, one or more symbolic links to the source database system are generated. The symbolic links identify a path to a physical location of the source database. A replica of the source database is generated based on the symbolic links. The replica includes a copy of the main index file and delta log file. Information associated with the replica and the symbolic links is stored in a recovery log. Replica are provided transparently to most database engine components by re-using partitioning infrastructure. Components “see” replica as tables with a single partition; that partition is a local replica.
摘要翻译：数据库中的数据复制包括识别源数据库系统。源数据库包括主索引文件和增量日志文件。要创建副本，将生成到源数据库系统的一个或多个符号链接。符号链接标识到源数据库的物理位置的路径。基于符号链接生成源数据库的副本。副本包括主索引文件和增量日志文件的副本。与副本和符号链接相关联的信息存储在恢复日志中。通过重新使用分区基础架构，对大多数数据库引擎组件透明地提供副本。组件“将”副本视为具有单个分区的表; 该分区是本地副本。

摘要： Embodiments of the present invention include in-memory processing for data warehouse applications. In one embodiment, data records from a data warehouse application are stored in a data storage structure of an in-memory database. Data received from the data warehouse may be stored in a queue and loaded into the data storage structure according to predefined rules. Stored data records are associated with in-memory database transactions that caused the stored data record to be stored, and may further be associated with transactions that caused the stored data records to be changed. A mapping is generated to associate requests from the data warehouse application with in-memory database transactions. The data warehouse application may retrieve data in a change data format calculated on-the-fly.

摘要： A request for at least a portion of a business object is received by a database from a client in a first half of a roundtrip between the client and the database. Each of the tables includes a primary key column and a plurality of records. The primary key column provides, for each record in the table, a primary key for one of a plurality of business objects. Thereafter, the database identifies records within a set of tables among a larger number of tables in the database by matching a primary key associated with the business object with the primary key in the primary key column. Once this identification has been made, the database obtains all values responsive to the request from the identified record and transmits, in a second half of the roundtrip between the client and the database, the obtained values for the business object to the client.
摘要翻译：在客户端和数据库之间的往返的前半部分，数据库从客户端接收对业务对象的至少一部分的请求。每个表包括主键列和多个记录。主键列为表中的每个记录提供了多个业务对象之一的主键。此后，数据库通过将与业务对象相关联的主键与主键列中的主键进行匹配来识别数据库中较大数量的表中的一组表内的记录。一旦进行了此识别，数据库就会根据来自所识别的记录的请求获取所有值，并在客户端和数据库之间的往返的后半部分中将所获得的业务对象的值发送给客户端。
