Multiple cache processing of streaming data

A data processing system comprising:

• one or more processors;
• a memory storing a program which, when executed on the processor, performs an operation for processing streaming data;
• a database repository;
• and
• a cache memory for the database repository,
• wherein the cache memory comprises:
• a first cache area used for carrying out, in a first time window, a role of receiving streaming data and writing the streaming data thereon without carrying out synchronization between the first cache area and the database repository;
• and
• a second cache area used for carrying out, in at least part of the first time window, a role of synchronization with the database repository;
• and
• wherein the data processing system carries out synchronization between the first cache area and the database repository upon elapse of the first time window.

A computer program product for processing streaming data, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, wherein the computer readable storage medium is not a transitory signal per se, the program instructions executable by a computer to cause the computer to perform a method comprising:

• providing a first cache area and a second cache area on a cache memory in a data processing system comprising a database repository and the cache memory for the database repository;
• receiving, in a first time window, streaming data and writing the streaming data on the first cache area;
• prohibiting, in the first time window, carrying out synchronization between the first cache area and the database repository;
• enabling, in at least part of the first time window, synchronization between the database repository and the second cache area;
• and
• enabling, upon elapse of the first time window, synchronization between the first cache area and the database repository.
