Abstract
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.
