  Transient radio sources, such as fast radio bursts, intermittent pulsars, and
rotating radio transients, can offer a wealth of information regarding extreme
emission physics as well as the intervening interstellar and/or intergalactic
medium. Vital steps towards understanding these objects include characterizing
their source populations and estimating their event rates across observing
frequencies. However, previous efforts have been undertaken mostly by
individual survey teams at disparate observing frequencies and telescopes, and
with non-uniform algorithms for searching and characterization. The Petabyte
Project (TPP) aims to address these issues by uniformly reprocessing data from
several petabytes of radio transient surveys covering two decades of observing
frequency (300 MHz-20 GHz). The TPP will provide robust event rate analyses,
in-depth assessment of survey and pipeline completeness, as well as revealing
discoveries from archival and ongoing radio surveys. We present an overview of
TPP's processing pipeline, scope, and our potential to make new discoveries.
