In some environments, = it requires compiling the natives from sources which is non-trivial. Also, = this approach is platform dependent; the binary may not work in different p= latform, so it requires recompilation. > * It requires extra configuration of *java.library.path* to load the nat= ives, and it results higher application deployment and maintenance cost for= users. > Projects such as *Spark* and *Parquet*=C2=A0use [snappy-java|[https://git= hub.com/xerial/snappy-java]] which is JNI-based implementation.
