Published by Grace Pierce Modified over 2 years ago. We present a system for automating such analyses. The intermediate value is combined sawzalll values from other records.

It generally breaks the calculation in two phases first phase analyses the record and second phase aggregates the result. The output of the program for each record is the intermediate value. The Definitive Guide Chap. A filtering phase, in which a query is expressed using a new programming language, emits data to an aggregation phase.

The daga is divided into pieces and distributed, keeping computation near data. Two phases for calculation -Analysis Phase -Aggregation Phase.

The main measurement is not single-CPU speed. Table of Contents Alerts. 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.

Sawzall is a statically typed language for processing very large amount of data on multiple machines. Which one is right? A filtering phase, in which a query is expressed sawzll a new procedural programming language, emits data to an aggregation phase.
