摘要： A computer receives one or more files having configuration information that includes data that defines a plurality of stages of an extract, transform, and load (ETL) job, wherein the plurality of stages comprise a read stage that is preceded by a write stage, and wherein the read stage reads data from a source location, and wherein the data that is read or a modified version of the data that is read is being written by the write stage that writes data to the source location. The computer replaces the read stage with a decompressor stage. The computer replaces the write stage with a compressor stage. The computer executes the decompressor stage and compressor stage on a field-programmable gate array that is programmatically customized with data compression and data decompression functionality to enhance the performance of the ETL job.

摘要： Performing an extract, transform, and load (ETL) process. Column data is received by a stage of the ETL process. The size of the received column data is ascertained by the stage. In response to determining that the size of the column data exceeds a predefined threshold, the stage saves the column data and creates a data locator associated with the column data. The created data locator advances through successive downstream stages of the ETL process as a replacement for the column data.

摘要： Disclosed aspects relate to data integration application execution management using both a set of managed nodes and a set of unmanaged nodes. An execution request for a data integration application may be sensed. A first set of commands of the data integration application may be assigned to the set of managed nodes. A second set of commands of the data integration application may be assigned to the set of unmanaged nodes. Execution of the data integration application may be initiated using the set of managed nodes to process the first set of commands and the set of unmanaged nodes to process the second set of commands.

摘要： Insertion, in a data warehouse process, of a buffer operator between an upstream data operator and a downstream data operator. The processor processes a data record for the upstream data operator to pass to the downstream data operator. In response to determining that the downstream data operator is not ready to accept the data record from the upstream data operator, a buffer operator is inserted between the upstream data operator and the downstream data operator. The data record processed by the upstream data operator is passed to the buffer operator for storing into a buffer allocated for use by the buffer operator. The data record stored into the buffer is passed to the downstream data operator when the downstream data operator is ready to accept data. In another aspect, when the allocated buffer utilization decreases to a threshold value, the buffer operator is removed and the buffers are released.

摘要： A discussion thread is associated with a master recipients list that is maintained at an author's computer or a server computer. The recipients list is revised as participants in the discussion are added to and/or removed from the discussion. An author is notified when target recipients do not match the master recipients list. When a participant is added to the discussion from an old discussion instance, a thread manager provides for the added participant to receive a more current discussion instance.

摘要： Provided are a computer program product, system, and method for allocating physical nodes for processes in an execution plan. An execution plan is generated indicating a plurality of processes. A resource requirement is generated indicating requested physical nodes and an assignment of the processes to execute on the requested physical nodes. A determination is made from the resource requirement of a resource allocation of physical nodes for the requested physical nodes and the processes. The execution plan is updated to generate an updated execution plan indicating the physical nodes on which the processes will execute according to the received resource allocation.
