Description
TeleScope CQ is the efficient intensive-load XML message stream broker and simple event processing platform (SEP) written in C for the Fedora 17-18, Slackware 13-14, Red Hat Enterprise Linux 6 (RHEL-6) Linux distributions.
The platform is intended to be operated upon the single number/word values and is not meant to be deployed for full-text XML stream analysis. TeleScope has internal query language with a set of standard logical operators that allows to construct relatively complex query expressions. The platform features the pub-sub architecture and serves up to 128 simultaneously connected XML stream subscribers. The broker features Continuous Query (CQ) engine over the XML message stream. TeleScope CQ provides the remote cli interface to login (in cisco fashion via telnet) and change/reset the query transaction on the current stream on the fly in real time. It also gives data query and subscribers statistics via a separate status port.
