Both phases are distributed over hundreds or ibterpreting thousands of computers. Protocol Buffers are used -To define the messages communicated between servers. We present a system for automating such analyses. A filtering phase, in which a query is expressed using a new programming language, emits data to an aggregation interprsting.

Interpreting the Data: Parallel Analysis with Sawzall – Google AI

The design — including the separation into two phases, the form of the programming language, and the properties of the aggregators — exploits the parallelism inherent in datta data and computation distributed across many machines. These large data sets are not amenable to study using traditional database techniques, if only because they can be too large to fit in a single relational database.

The results are then collated and saved to a file. Assume certain things about the problem space Hide details about: A filtering phase, in which a query is expressed using a new procedural programming language, emits data to an aggregation phase. Code taken from the paper.

Figure taken from paper. Sawzall is faster than Python, Ruby and Perl. Two phases for calculation -Analysis Phase -Aggregation Phase. The paper is from the organization Google which is popular for their capabilities for massive computation on Data and is about the sadzall they are using to solve day to day problems in Google.

The design — including the separation into two phases, the form of the programming language, and the properties of the aggregators — exploits the parallelism inherent in having data and computation distributed across many machines. Sawzall is also a level of abstraction above MapReduce, but still appears to be a bit more restrictive than Pig Latin [1].
