US Patent 7246227 Efficient scanning of stream based data

Methods, systems, and computer readable media utilize a stream manager (101) to efficiently scan stream (105) based data (103). A stream manager (101) receives (801) data (103) from a stream (105). The stream manager (101) makes (807) received data (103) serially available to a plurality of modify scanners (109) in a specific order, and makes (809) received data (103) available in parallel to a plurality of read-only scanners (111). The stream manager (101), responsive to data (103) having been released by each modify scanner (109) of the plurality and by each read-only scanner (111) of the plurality, transmits (515) released data (103) to a destination (113).
