teering is similar to the Unix tee program. Where tee takes its standard input and outputs it to a file as well as its standard output, teeringtakes as input ringbuffer items, and outputs them both to a ring buffer and standard output.
The intent of teering is to provide you with the ability to create test points along the path of a pipeline that transforms data from one set of ring items to another. A sample use of teering is to provide a test point for the ordered event fragments emitted from the event orderer before glom is used to build events.
teering has a single command option
that is required: --ring
's argument provides the
name of the ring into which teering will
output data.
