Dhaliyaha UUID v7
Ku dhaliso qiyamka UUID v7 khadka tooska ah: UUID-yo waqti ahaan loo kala saari karo oo leh 48-bit millisekond shaambada waqtiga ah iyo 74 bits oo kala-sooc la'aan ah.
ID-yada la dhalay
Sida ID-gan loo dhisay
- Qaabka (Layout)
- 48-bit Unix millisekond shaambada waqtiga ah, nooca 7 bits, bits kala-duwan oo RFC ah iyo buuxin kala-sooc la'aan ah.
- Entropy
- 74 bits oo kala-sooc la'aan ah hirgelintan dhexdeeda; ma jiro miiska monotonic.
- Waqtiga
- Haa. 48-ka bits ee ugu horreeya waxay codeeyaan waqtiga la sameeyay, markaa ID-yada waxaa loo kala saaraa waqti ahaan millisekond-yo kala duwan.
- Khatarta isku-dhaca
- Hal millisekond gudaheed, isku-dhacyadu waxay ku xiran yihiin 74 bits oo kala-sooc la'aan ah; mugga aadka u sarreeya ee isku mid ms ah waa inuu isticmaalaa adeeg ID oo la isku duway.

ID-yadaada waxaa lagu dhaliyaa gudaha iyadoo la isticmaalayo habka kala-sooc la'aanta adag ee biraawsarka. Waxba looma soo diro BroBroGo.
Su'aalaha badanaa la isweydiiyo (FAQ)
Maxay tahay sababta loo dooranayo UUID v7 halkii laga dooran lahaa UUID v4?
UUID v7 wuxuu ilaalinayaa qaabka UUID laakiin wuxuu u kala saaraa waqti ahaan, taas oo caawin karta logs, tusmooyinka kaydka xogta (database indexes) iyo qulqulka dhacdooyinka inay ahaadaan kuwo taariikhi ah.
UUID v7 ma qariyaa waqtiga la sameeyay?
Maya. Shaambada waqtiga waa qayb ka mid ah ID-ga. Isticmaal UUID v4 ama NanoID haddii aad u baahan tahay aqoonsi qarsoon oo aan lahayn xogta waqtiga.
