July 31, 2013 | 3 Thinking Beyond Search with Solr – Understanding How Solr Can Help Your Business Scale

What is Apache Solr?


Solr • Separate application – installed on its own server, or

on an existing server in the environment depending on

business needs.

• Solr uses schema configuration files which can be

found in Magentto/lib/Apache

• Magento communicates with Solr via HTTP/XML

• Searching options configured via the Magento admin

panel


What is Apache Solr? General Solr Overview

Better text-based searching provides a better customer experience • More relevant “fuzzy” searching*

• Faceted searches

• Search corrections

• Out of the box type-ahead*

• Response caching for better performance

Thinking Beyond Search with Solr – Understanding How Solr Can Help Your Business Scale

*Requires customization to leverage at 100%

What is Apache Solr? Solr the Search Platform

Solr is more than a search engine because… • Most data customers see is handled by

Solr instead of MySQL


What is Apache Solr? What Makes Solr Powerful



• Solr uses a simpler data structure



product_id attribute_id product_id attribute_name

attribute_id product_id attribute_value

product_id attribute_name attribute_value

MySQL (EAV)

Solr (No EAV)



• Solr uses a simpler data structure

• Solr supports replication which allows it to

truly scale for growth

Supporting Initial Catalog Growth


Business Background • Growing catalog – from 10K to 100K SKUs

• From 1 to 2 stores

• From 1 to 2+ web nodes / 1 database node

• Using native Solr Search


Problems • Increased indexing time

• Out-dated information on the front-end

Business Use Case Supporting Initial Catalog Growth

Concept

• Connects to the database using JDBC

• Extra data transformations must be

written in Java/JavaScript.

• Uses a prepared xml configuration

Supporting Initial Catalog Growth Solution – Custom Data Import Handler


Results • 10 times faster indexing

• Supports delta-indexing


Supporting Initial Catalog Growth Data Import Handler – Results

Things to keep in mind • Solr knows about its data source

• May require extra development efforts

• Extra data transformations must be

written in Java/JavaScript

Supporting Growing Traffic


Business Background • Growing catalog – 1,000,000 SKUs

• Growing traffic: up to 100 requests / second

• 3 stores

• 3+ web nodes/ 1 database node

• Using Data Import Handler


Problem • Solr can’t handle increasing user

concurrency

Supporting Growing Traffic Problem – Increased Response Time


July 31, 2013 | 19

Supporting Growing Traffic Solution – Solr Replication

Concept • Separate reading requests

• Replicate index across multiple nodes

• Read from multiple servers


Results • Allows Solr to handle read traffic

• Introduces fail-over

Things to keep in mind • Requires middle-ware or Magento customization

• Possible heavy data duplication

• Extra changes in infrastructure

Supporting Initial Catalog Growth Solr Replication – Results


Supporting Substantial Catalog Growth



• 4 stores

• 4+ web nodes / 1 database node

• Using Data Import Handler

• Using Solr replication


Problems • Delta-indexing delays

• Slow response time

Concept

• Distributed search

• Distributed + Replication

(SolrCloud)


Supporting Substantial Catalog Growth Solution – Index Sharding

Results • Distributed search for faster response time

• 50 times faster indexing with 5 shards

• Extra changes in infrastructure

Supporting A Real-Time Catalog



• 5 stores

• 5+ web nodes / 1 database node

• Data Import Handler

• SolrCloud and distributed search


Business Requirement • Always up-to-date index

Business Use Case Supporting A Real-Time Catalog

Supporting A Real-Time Catalog Solution – Listen To The MySQL Bin Log

July 31, 2013 | 29

Concept • Connect via MySql replication protocol

• Listen to data-related events

• Listen to data-related events

• Extract information from events

• Manipulate with document in Lucene index

Key Points to Remember


• Solr’s search capabilities provide a better site experience than MySQL LIKE or Full-text

• Solr is more than a search platform – it is a key for scalability and growth

• Solr’s data import handler keeps Solr performing well as your catalog grows

• Solr replication helps accommodate growing traffic

• Solr shards help keep indexing execution time and search response times low for very

large catalogs

• Listening to the MySQL bin log can help facilitate a continuously updating catalog


Key Points to Remember Solr helps businesses scale
