Abstract:
1. A method for filtering data in an incoming write data request, comprising: a computer, receiving a write data request by a filter write controller in a write layer of a database management system, the write data request passed to the filter write controller from a request interface of the database management system that receives a plurality of write data requests from one or more applications requesting to write data to one or more tables from among a plurality of tables of a database; the computer, responsive to the filter write controller receiving the write data request, determining whether a particular filter list in the write layer, associated with a particular table from among the plurality of tables specified in the write data request, comprises at least one filter rule, from among a plurality of filter lists each associated with a separate table from among the plurality of tables; the computer, responsive to detecting the particular filter list associated with the particular table comprises the at least one filter rule, evaluating content of the at least one record of the write data request for the particular table, against the at least one filter rule specified for the particular table in the particular filter list; and the computer selecting, by the filter write controller, whether to allow storage of the at least one record of the write data request as a separate row in the particular table based on a separate action triggered for the at least one record when evaluated against the at least one filter rule specified for the particular table, each record not selected for storage being silently discarded.
