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
