Gupta et al. [11] studied the problem of handling multi-way spatial join queries on map-reduce platform and proposed the
Controlled-Replicate
algorithm for the same. In this paper we present
ε-Controlled-Replicate
- an improved
Controlled-Replicate
procedure for processing multi-way spatial join queries on map-reduce. We show that
ε-Controlled-Replicate
algorithm presented in this paper involves a significantly smaller communication cost vis-a-vis
Controlled-Replicate
. We discuss the details of
ε-Controlled-Replicate
algorithm and through an experimental study over synthetic as well as real-life California road datasets, we show the efficacy of the
ε-Controlled-Replicate
algorithm vis-a-vis
Controlled-Replicate
.
