Cov ntaub ntawv ingestion yog tus txheej txheem ntawm tau txais thiab importing cov ntaub ntawv rau kev siv tam sim lossis khaws cia rau hauv ib lub database. Txhawm rau noj ib yam dab tsi yog "coj ib yam dab tsi los yog nqus ib yam dab tsi." Cov ntaub ntawv tau streamed nyob rau hauv lub sij hawm los yog noj hauv batch.
Kuj paub, dab tsi yog cov ntaub ntawv ingestion pipeline?
Data Ingestion Pipeline . A cov ntaub ntawv ingestion pipeline txav streaming cov ntaub ntawv thiab batched cov ntaub ntawv los ntawm cov ntaub ntawv uas twb muaj lawm thiab cov ntaub ntawv warehouses rau a cov ntaub ntawv pas dej. Rau HDFS-based cov ntaub ntawv pas dej, cov cuab yeej xws li Kafka, Hive, lossis Spark yog siv rau cov ntaub ntawv ingestion . Kafka yog nrov cov ntaub ntawv ingestion cuab tam uas txhawb streaming cov ntaub ntawv.
Tsis tas li ntawd, Hadoop ingest cov ntaub ntawv li cas? Hadoop siv cov ntaub ntawv faib tawm uas zoo rau kev nyeem ntawv thiab sau cov ntaub ntawv loj. Thaum sau ntawv rau HDFS , cov ntaub ntawv yog "sliced" thiab replicated hla cov servers hauv a Hadoop pawg. Cov txheej txheem slicing tsim ntau qhov me me (blocks) ntawm cov ntaub ntawv loj dua thiab pob tshab sau rau hauv pawg nodes.
Secondly, dab tsi yog cov ntaub ntawv ingestion cuab yeej?
Cov cuab yeej siv cov ntaub ntawv muab lub moj khaum uas tso cai rau cov tuam txhab sau, xa tawm, thauj khoom, hloov pauv, sib koom ua ke, thiab txheej txheem cov ntaub ntawv los ntawm ntau yam ntawm cov ntaub ntawv qhov chaw. Lawv pab txhawb cov cov ntaub ntawv extraction txheej txheem los ntawm kev txhawb ntau yam cov ntaub ntawv thauj cov txheej txheem.
Koj txoj kev nkag siab ntawm kev noj cov ntaub ntawv thiab kev koom ua ke yog dab tsi?
Cov ntaub ntawv ingestion yog tus txheej txheem ntawm noj cov ntaub ntawv los ntawm ib qho system mus rau lwm qhov. Kev koom ua ke cov ntaub ntawv tso cai sib txawv cov ntaub ntawv hom (xws li cov ntaub ntawv teeb, cov ntaub ntawv thiab cov rooj) kom muab sib xyaw thiab siv los ntawm cov ntawv thov rau kev ua haujlwm ntawm tus kheej lossis kev lag luam.

Lub voj voog kev sib txuas lus hauv kev noj qab haus huv thiab kev noj qab haus huv yog dab tsi?
Ob lub ntsiab lus tseem ceeb uas cov neeg ua haujlwm saib xyuas kev noj qab haus huv thiab kev noj qab haus huv siv lub voj voog sib txuas lus yog ib-rau-ib thiab kev sib txuas lus hauv pab pawg. Cov neeg ua haujlwm saib xyuas tham nrog cov npoj yaig ua haujlwm, rau cov neeg siv cov kev pabcuam saib xyuas thiab rau lawv cov txheeb ze ntawm ib-rau-ib feem ntau zaus hauv ib hnub
Vim li cas nws tseem ceeb kom khaws cov ntaub ntawv tsis pub lwm tus paub hauv kev noj qab haus huv thiab kev saib xyuas kev noj qab haus huv?
Ib qho tseem ceeb tshaj plaws ntawm kev ceev ntiag tug yog tias nws pab tsim thiab txhim kho kev ntseeg siab. Nws muaj peev xwm tso cai rau cov ntaub ntawv pub dawb ntawm cov neeg siv khoom thiab cov neeg ua haujlwm thiab lees paub tias tus neeg siv khoom lub neej thiab txhua yam teeb meem thiab teeb meem uas lawv muaj rau lawv
Dab tsi ntawm cov hauv qab no yog cov txheej txheem kev tshuaj xyuas cov ntaub ntawv hauv kev tshawb fawb zoo?
Cov txheej txheem kev txheeb xyuas cov ntaub ntawv feem ntau siv yog: Kev tsom xam cov ntsiab lus: Qhov no yog ib txoj hauv kev zoo tshaj plaws los tshuaj xyuas cov ntaub ntawv zoo. Kev txheeb xyuas cov lus piav qhia: Txoj kev no yog siv los txheeb xyuas cov ntsiab lus los ntawm ntau qhov chaw, xws li kev xam phaj ntawm cov neeg teb, kev soj ntsuam los ntawm thaj chaw, lossis kev tshawb fawb
Dab tsi yog cov teeb meem ntawm kev tswj cov ntaub ntawv hauv cov ntaub ntawv ib txwm muaj?
Nyob rau tib lub sijhawm, qhov kev tswj hwm cov ntaub ntawv ib puag ncig tsim teeb meem xws li cov ntaub ntawv rov ua dua thiab tsis sib xws, cov kev pab cuam-cov ntaub ntawv dependence, inflexibility, tsis muaj kev ruaj ntseg, thiab tsis muaj cov ntaub ntawv sib qhia thiab muaj
Txoj hauv kev zoo tshaj plaws rau daim ntawv thov upload cov ntaub ntawv loj hauv s3 yog dab tsi?
Cov ntaub ntawv loj tshaj plaws uas tuaj yeem muab tso rau hauv Amazon S3 thoob hauv ib qho kev ua haujlwm PUT yog 5 GB. Yog tias koj xav upload cov khoom loj (> 5 GB), koj yuav txiav txim siab siv multipart upload API, uas tso cai rau upload cov khoom ntawm 5 MB mus txog 5 TB
