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.
