| Sr. No | Hais kom ua & Nqe lus piav qhia |
|---|---|
| 10 | PERSIST qhov tseem ceeb Tshem tawm lub sijhawm kawg los ntawm tus yuam sij . |
| 11 | PTTL tus yuam sij Tau txais lub sijhawm seem hauv cov yuam sij tas sij hawm hauv milliseconds. |
| 12 | TTL yuam sij Tau txais lub sijhawm seem hauv cov yuam sij tas sij hawm. |
| 13 | RANDOMKEY Rov qab ib qho random tus yuam sij los ntawm Redis . |
Xav txog qhov no, kuv yuav paub li cas thaum kuv tus yuam sij Redis tas sij hawm?
Ua ntej, tsim ib tus yuam sij hauv redis thiab teem ib co nqi nyob rau hauv nws. Tam sim no teeb lub tas sij hawm ntawm tus yuam sij thiab tom qab ntawd xwb kuaj qhov seem tas sij hawm sij hawm. Ua ntej, tsim ib tus yuam sij hauv redis thiab teem ib co nqi nyob rau hauv nws. Tam sim no teeb lub tas sij hawm ntawm tus yuam sij , thiab tom qab ntawd xwb kuaj qhov seem tas sij hawm sij hawm.
Tsis tas li ntawd, setex yog dab tsi? Kev tshaj tawm. Redis SETEX hais kom ua yog siv los teeb tsa qee txoj hlua tus nqi nrog lub sijhawm teem sijhawm hauv Redis tus yuam sij.
Ib yam li ib tug yuav nug, Redis yuav ua haujlwm li cas?
Redis cov yuam sij yog tas sij hawm nyob rau hauv ob txoj kev: ib tug passive txoj kev, thiab ib tug active txoj kev. Ib qho tseem ceeb yog passively tas sij hawm tsuas yog thaum qee tus neeg siv khoom sim nkag mus rau nws, thiab tus yuam sij tau pom tias yuav raug ncua sijhawm. Tshwj xeeb yog qhov no Redis ua 10 zaug ib ob: Xeem 20 yuam sij random los ntawm cov yuam sij txheej nrog ib qho cuam tshuam tas sij hawm.
Yuav ua li cas ntxuav Redis?
Hauv Redis koj ua tau yaug cache/database thiab rho tawm tag nrho cov yuam sij los ntawm tag nrho cov databases lossis los ntawm cov ntaub ntawv tshwj xeeb tsuas yog siv FLUSHALL thiab FLUSHDB cov lus txib. Txhawm rau rho tawm txhua tus yuam sij ntawm txhua tus Redis databases, siv FLUSHALL hais kom ua. Txhawm rau tshem tawm tag nrho cov yuam sij ntawm cov xaiv Redis database nkaus xwb, siv FLUSHDB commnad.

Dab tsi ntawm algorithms xav kom tus neeg xa khoom thiab tus neeg txais kev sib pauv hloov tus yuam sij zais cia uas siv los xyuas kom meej qhov tsis pub lwm tus paub ntawm cov lus?
Dab tsi ntawm algorithms xav kom tus neeg xa khoom thiab tus neeg txais kev sib pauv pauv tus yuam sij zais cia uas siv los xyuas kom tsis pub leej twg paub cov lus? Kev piav qhia: Symmetrical algorithms siv tib tus yuam sij, tus yuam sij zais cia, los encrypt thiab decrypt cov ntaub ntawv. Tus yuam sij no yuav tsum tau muab qhia ua ntej ua ntej kev sib txuas lus tuaj yeem tshwm sim
Dab tsi yog tus yuam sij ntiag tug thiab pej xeem tus yuam sij hauv Blockchain?
Thaum ib tug neeg xa koj cryptocoins hla Blockchain, lawv tau xa lawv mus rau qhov hashed version ntawm qhov hu ua "Public Key". Muaj lwm tus yuam sij uas zais ntawm lawv, uas yog hu ua "Private Key." Qhov Private Key no yog siv los muab Public Key
Koj txhais li cas los ntawm tus yuam sij ntiag tug thiab pej xeem tus yuam sij cryptography?
Nyob rau hauv pej xeem tus yuam sij cryptography, ob tus yuam sij yog siv, ib tug yuam sij yog siv rau encryption thiab thaum lwm yam yog siv rau decryption. 3. Nyob rau hauv private keycryptography, tus yuam sij yog khaws cia tsis pub leejtwg paub. Nyob rau hauv pej xeem tus yuam sij cryptography, ib qho ntawm ob tus yuam sij yog khaws cia tsis pub leejtwg paub
Koj txhais li cas compile lub sij hawm tas li hauv Java Dab tsi yog siv compile lub sij hawm tas li?
Compile-time constants thiab variables. Cov ntaub ntawv Java hais tias: Yog hais tias ib hom thawj zaug los yog ib txoj hlua txhais tau tias yog qhov tas li thiab tus nqi raug paub thaum lub sij hawm sau, lub compiler hloov lub npe tas li txhua qhov chaw hauv cov cai nrog nws tus nqi. Qhov no yog hu ua compile-time constant
