InlineQuerier: A Mid-Stream FME Database

April 2012

InlineQuerier: Motivation

Cascading FeatureMergers = BAD

InlineQuerier: Motivation

Cascading FeatureMergers = BAD Each FeatureMerger causes features to be

Blocked up Reindexed Re-cached to disk

Joins between features are limited to a single key No sophisticated ability to compute additional

values or configure the join FeatureMergers join only two streams at a time

InlineQuerier: Introduction

Fully configurable multi-stream join Brings SQL power to all datasources

Cache and index once Query many times

Extract, Join, & Computeinformation via SQL Query

Tidier workspaces Improved performance
