Consumption Derivations / Calculations Added Metastore Added Raw Layer β€’Β Data in nearly organized form β€’ No transformations Figure 2: Partitioned Object Storage with Hive Clustering enhance access patterns depicted in Figure 2. Much more could be written about this one example; suffice to say that many additional layering approaches can be implemented depending on the desired consumption patterns. Choose File Format Introduction People coming from the traditional RDBMS world are often surprised at the extraordinary amount of con- trol that we as architects of data lakes have over exactly how to store data. We, as opposed to an RDBMS storage engine, get to determine an array of elements such as file sizes, type of storage (row vs. columnar), degree of compression, indexing, sche- mas, and block sizes.
