There are five publisher and subscriber executables: esp_convert , esp_kdbin, esp_kdbout, esp_subscribe, and
esp_upload .
- esp_convert –
reads XML or delimited records from standard input
and produces binary format records on standard output.
- esp_kdbin – reads data from a KDB database table into an
Event Stream Processor stream.
- esp_kdbout – feeds streaming data from the Event Stream Processor to a KDB
database table.
- esp_subscribe – connects to a running instance of the ESP Server
and subscribes to streaming data. The received records are converted to XML (or
optionally delimited format) and written to standard output.
- esp_upload – reads binary records from standard input and publishes them to a current
instance of the Event Stream Processor through the Gateway
interface.
