What is it about?
It's Big Data era. In this epoch, the terabytes of data are a dime a dozen as well as large metadata size. The large scale metadata size becomes a barrier in the era of exascale computation. However, a fine-tuning, and a well designing of metadata can enhance the performance of a file system. Therefore, the large scale metadata server (MDS) design becomes key research point now-a-days. The designing MDS becomes a prominent challenge when metadata size grows and becomes unmanageable. Besides, the metadata management becomes also a challenging task in serving very large scale metadata. The distributed Metadata Servers (dMDS) are becoming mature enough to serve huge sized metadata. In this paper, we present state-of-the-art metadata server technology. Moreover, the paper encompasses the issues, and challenges of dMDS.
