HBase yog cov ntaub ntawv qauv zoo ib yam li Google lub rooj loj uas yog tsim los muab random nkag mus rau qhov ntim siab ntawm cov ntaub ntawv tsim los yog tsis muaj qauv. HBase yog ib feem tseem ceeb ntawm cov Hadoop ecosystem uas leverages qhov txhaum kam rau ua feature ntawm HDFS . HBase muab lub sijhawm nyeem ntawv lossis sau ntawv nkag mus rau cov ntaub ntawv hauv HDFS.
Ib sab ntawm no, vim li cas HBase siv hauv Hadoop?
HBase yog hu ua Hadoop database vim nws yog NoSQL database uas sau rau saum Hadoop . Nws combines lub scalability ntawm Hadoop los ntawm kev khiav ntawm lub Hadoop Distributed File System (HDFS), nrog rau cov ntaub ntawv ntawm lub sijhawm nkag mus ua lub khw tseem ceeb / tus nqi thiab muaj peev xwm sib sib zog nqus ntawm Daim Ntawv Qhia Txo.
Ib yam li ntawd, qhov txawv ntawm HBase thiab Hadoop yog dab tsi? Hadoop thiab HBase ob leeg siv los khaws cov ntaub ntawv ntau heev. Tab sis lub txawv yog in Hadoop Distributed File System (HDFS) cov ntaub ntawv khaws cia yog ib qho kev faib thoob plaws txawv nodes ntawm lub network ntawd. Txawm li cas los xij, HBase yog database uas khaws cov ntaub ntawv hauv daim ntawv ntawm kab thiab kab hauv a Rooj.
Kuj nug, yog HBase ib feem ntawm Hadoop?
HBase yog ib tug faib kem-oriented database ua rau saum Hadoop cov ntaub ntawv system. Nws yog ib ib feem ntawm Hadoop ecosystem uas muab random real-time nyeem / sau nkag mus rau cov ntaub ntawv nyob rau hauv lub Hadoop Cov ntaub ntawv System. Ib tus tuaj yeem khaws cov ntaub ntawv hauv HDFS ncaj qha lossis dhau los HBase.
Lub luag haujlwm ntawm ZooKeeper hauv HBase yog dab tsi?
ZooKeeper : Hauv HBase , Zookeeper yog ib tug centralized saib xyuas neeg rau zaub mov uas tswj cov ntaub ntawv configuration thiab muab faib synchronization. Distributed synchronization yog nkag mus rau cov ntawv thov faib ua haujlwm thoob plaws pawg nrog lub luag haujlwm ntawm kev muab kev pabcuam kev sib koom tes ntawm cov nodes.
