1. แนะนะเกี่ยวกับ Apache Solr 4.0 2. การใช้งาน Admin 3. การ Scale ระบบงาน 4. เครื่องมือการทดสอบประสิทธิภาพ 5. การ tunning ขั้นพื้นฐาน

1. Apache Solr
@somkiat

2. Apache Solr
Search server
Based on Lucene
Full-text search library
Java 100%
Open source

3. Apache Solr
REST API
HTTP
XML
JSON

4. Apache Solr
Client supports
.NET
Java
PHP
Ruby
Python

5. How we
implement ?

6. SELECT *
FROM product
WHERE id LIKE ‘%1%’
AND name LIKE ‘%xxx%’

7. Problems
Full table scan = Killer performance
RDBMS is not designed for search
like that

8. Architecture
Query
WEB
Application
Apache
Solr
Result
Update
Indexer

9. How to use ?
Install
Define solrconfig.xml
Define schema.xml
Deploy to Java Web Server
Jetty ( Default )
Apache Tomcat

10. Define schema.xml
Structure of data
Liked table structure
Must have Primary/Unique key
Must have _version_ field

11. <field name="id" type="string"
indexed="true" stored="true"
required="true" />
!
<field name="item_id" type="string"
indexed="true" stored="true"
required="true" />
<uniqueKey>id</uniqueKey>

18. Scaling Solr
Scale up
CPU, RAM, SSD
Scale horizontal
(http:/
/wiki.apache.org/solr/DistributedSearch)
Scale deep
Sharding and Multiple replicate

23. JVM Memory
-Xms1024M -Xmx1024M -server

24. Virtual Memory
Virtual memory for index
Config in solrconfig.xml
<directoryFactory/>
change from
StandardDirectoryFactory to
MmapDirectoryFactory

25. Enable http caching
Config in solrconfig.xml

26. <httpCaching
lastModifiedFrom="openTime"
etagSeed="Solr"
never304="false">
<cacheControl>
max-age=43200, must-revalidate
</cacheControl>
!
</httpCaching>
