Byk Veri Nedir?

Big data(byk veri) genel olarak yksek hacimlerdeki veriler iin kullanlan bir terimdir.

Volume(Veri Hacmi)

Bu zellik verinin yksek hacimli olduunu belirtir

Velocity(Veri hz)

Veriler o kadar hzl retilmektedir ki , bir dakika ierisinde 200+ milyon e-mail , 4+ milyon Facebook like , 1+ milyon Instagram like ilemi yaplmaktadr

Variety(Veri eitlilii)

Verilerin belirli bir yaps yoktur, genellikle deikendir.Resimler, ses dosyalar, text dosyalar

Hadoop Nedir ?

Hadoop , byk veri kmeleri ile birden fazla makinada paralel olarak ilem yapmamz salayan Java ile yazlm ak kaynak kodlu ktphanedir

Hadoop Hdfs Nedir ?

Hadoop ierisinde byk verileri sakladmz bileene HDFS (Hadoop Distributed File System) denir

Hadoop MapReduce Nedir?

Hadoop ierisinde byk verileri paralel olarak ileyebileceimiz bileene MapReduce denir .


Kullanm Senaryolar

rnek Analizler

Son bir saat ierisinde 50 den fazla reklama tklayan kullanclar

Referer_url bilgisinden arama yaplan anahtar kelimelerin bulunmas

Tavsiye motoru (Mzik siteleri , sinema siteleri , alveri siteleri)

Network zerinde anormal durumlar (fraud , anomaly detection)

Reklam gsterimleri (Ad-network)

Apache Spark

Apache Spark byk verileri datk makinalarda ilemek iin kullanlan bir ktphanedir

Apache Spark

2009 ylnda UC Berkeley ' de gelitiriliyor

Hadoop ile karlatrldnda 10(x) disk ve 100(x) memory hzl

Java, Scala, Python, R

u an Apache Software Foundation altnda gelitiriliyor

2014 ylnda TLP(Top Level Project) olarak duyuruluyor

Apache Spark Bileenleri

Apache Spark Mimarisi

RDD, DataFrame, DataSet

Verileri cluster zerinde saklayarak paralel olarak ilemler yapmamz salar

RDD

Datk(Distributed) JVM nesneleridir

map,reduce,count,groupBy,filter,join,saveAsTextFile .. gibi metodlar salar

DataFrame

Spark 1.3 ile gelmitir

RDD ye gre performans daha iyidir . SQL benzeri sorgular altrlabilir.

DataSet

Spark 1.6 ile gelmitir

Type-safe salar ,hatalar compile time da gsterir

Memory zerinde daha az yer kaplar

RDD ' ye gre hzldr

Encoder yaps deimitir

Spark Streaming

Gelen verileri anlk olarak(real time) analiz etmemizi salar

Toplad verileri parametrik olarak window lara ayrr (window1,window2...)

MLib

leklenebilir machine learning ktphaneleri mevcuttur

Java, Scala, Python ve R ile gelitirilebilir

Logistic regression

Gelen e-mailler ierisinde spam olanlar belirlenebilir

Clustering

K-means ile network verileri zerinde anormal ataklarn(anomaly detection) bulunmas

Recomendation

ALS ile bireylerin davranlarnn birbirlerine benzetilerek film,mzik.. nerisi

K-means

ALS
