Redshift yog ib tug tswj cov ntaub ntawv warehouse muab los ntawm Amazon Web Services . Ib qho ntawm nws cov yam ntxwv tseem ceeb, thiab ib feem ntawm qhov zais cia tom qab nws qhov kev ua tau zoo, yog nws columnar cov ntaub ntawv qauv.
Ib yam li ntawd ib tug yuav nug, yog redshift ib columnar?
1 Teb. Koj hais yog lawm -- Amazon Redshift yog a columnar database. Qhov no txhais tau hais tias cov ntaub ntawv khaws cia rau hauv disk ib kem, ua haujlwm ntawm ib kem ceev heev. Piv txwv li, ntxiv cov Sales kem rau ib qho nqi nyob rau hauv lub teb chaws kem tsuas yog yuav tsum tau nkag mus rau ob kab es tsis yog txhua kab hauv ib lub rooj.
Tsis tas li ntawd, AWS redshift siv rau dab tsi? Amazon Redshift yog ib tug tag nrho-tswj petabyte-scale huab raws li cov ntaub ntawv warehouse khoom tsim los rau loj teev cov ntaub ntawv teev cia thiab tsom xam. Nws kuj yog siv rau ua loj scale database migrations.
Tib neeg kuj nug, yog redshift heev muaj?
Redshift Spectrum yog ib qho ntawm Amazon Redshift uas ua rau koj khiav cov lus nug tawm tsam exabytes ntawm cov ntaub ntawv tsis tsim nyog hauv Amazon S3, tsis muaj kev thauj khoom lossis ETL xav tau. Koj tuaj yeem teeb tsa ntau li Amazon Redshift pawg raws li koj xav tau nug koj Amazon S3 cov ntaub ntawv pas dej, muab muaj ntau thiab limitless concurrency.
redshift cov ntaub ntawv khaws cia nyob qhov twg?
