摘要： A system, method, and computer readable medium are provided for reducing response time variation in a workload management system for a database system. When a query response is generated in response to a database query from a client, a determination may be made as to whether response time of the query response is less than a predetermined amount of time. Delivery of the query response to the client is delayed when an amount of time associated with the query response is less than the predetermined amount of time.

摘要： A temporal table is present in an active data warehouse (“ADW”) on a massively parallel processing system (“MPP system”). The MPP system includes a plurality of units of parallelism. Each of the plurality of units of parallelism maintains its own moving system time separate from that of the other units of parallelism. A load-job for the ADW is accepted. The load-job includes a requested modification to an identified row. The identified row is stored in the temporal table on a first of the MPP system's units of parallelism. The requested modification is implemented on the identified row. The identified row is timestamped with the moving system time maintained by the first of the MPP system's units of parallelism at the time of the implementation of the modification.

摘要： A method, computer program, and database system are disclosed. A plurality of instances of a request to a database system are received. All instances of the request have a same set of variables to use in executing the request. The values of the variables are supplied by data in a data source. A specific plan for executing one instance of the request is generated. Generating the specific plan includes taking into account data in the data source. The specific plan is executed on the database system. A system run-time metric and a parsing time for executing the specific plan are captured and saved. A generic plan is generated and cached based on a comparison of the system run-time metric and the parsing time for executing the specific plan.

摘要： Various embodiments may include taking an initial dump of a database table and tracking changes to the database table, with regard to but outside of transactions, since a most recent full or partial dump has been taken. A partial dump, in such embodiments, may be taken since the most recent full or partial dump and used to create a data structure which may be used to update only those database table rows modified since a last full or partial dump. As a result, the dumps of a database table will include a single full dump and may include one or more partial dumps. These full and partial dumps may then be instantiated to create or update an instance of the database table. In some embodiments, dumps may be taken directly to a mirrored instance of a database table.

摘要： A method of archiving a set of source tables in a database system. Each source table has a plurality of rows. Initially, a consistency point for the set of source tables is established. The database system creates a log record for each change (insert, modify, or delete) effected to a row of the source tables subsequent to the consistency point. Substantially all source table rows are copied to an archive (a data storage object that is external to the database system). Then the accumulated log records for the affected source tables are distilled and appended to the archive.

摘要： Implementations of a partitioned database system and a method of using a database system are disclosed. One system implementation includes storage facilities. Each storage facility includes data from database table rows. The database table rows in each storage facility that correspond to a specific database table are logically ordered according to a row identifier (row ID). The row ID includes a first value that is based on one or more columns of the table. The row ID also includes a second value that is based on one or more columns of the table, which may be different from or the same as those on which the first value is based. The first value of the row ID is predominate in determining the order of the rows in the storage facilities. The second value determines the order of those rows with identical first values.

摘要： A method, apparatus, and article of manufacture for accessing data in a computer system. One or more user-defined functions (UDFs) implementing a desired compression or decompression algorithm are created, wherein the UDFs are associated with one or more columns of a table when the table is created or altered, in order to perform compression or decompression of data stored in the associated columns, such that the data is compressed by the UDF implementing the desired compression algorithm when the data is inserted or updated in the table, and the data is decompressed by the UDF implementing the desired decompression algorithm when the data is retrieved from the table.
