Versatility of NewSQL databases is to achieve low latency constrains as well as to reduce cost commodity nodes. Out work emphasize on how big data is addressed through top NewSQL databases considering their features. This NewSQL databases paper conveys some of the top NewSQL databases [54] features collection considering high demand and usage. First part, around 11 NewSQL databases have been investigated for eliciting, comparing and examining their features so that they might assist to observe high hierarchy of NewSQL databases and to reveal their similarities and their differences. Our taxonomy involves four types categories in terms of how NewSQL databases handle, and process big data considering technologies are offered or supported. Advantages and disadvantages are conveyed in this survey for each of NewSQL databases. At second part, we register our findings based on several categories and aspects: first, by our first taxonomy which sees features characteristics are either functional or non-functional. A second taxonomy moved into another aspect regarding data integrity and data manipulation; we found data features classified based on supervised, semi-supervised, or unsupervised. Third taxonomy was about how diverse each single NewSQL database can deal with different types of databases. Surprisingly, Not only do NewSQL databases process regular (raw) data, but also they are stringent enough to afford diverse type of data such as historical and vertical distributed system, real-time, streaming, and timestamp databases. Thereby we release NewSQL databases are significant enough to survive and associate with other technologies to support other database types such as NoSQL, traditional, distributed system, and semirelationship to be as our fourth taxonomy-based. We strive to visualize our results for the former categories and the latter using chart graph. Eventually, NewSQL databases motivate us to analyze its big data throughput and we could classify them into good data or bad data. We conclude this paper with couple suggestions in how to manage big data using Predictable Analytics and other techniques.
