UUID Generator — frequently asked questions
v4 or v7?+
v4 is fully random. v7 embeds a timestamp so the IDs sort chronologically — better as database keys.
Are these guaranteed unique?+
v4 has ~5.3×10^36 possibilities, so collisions are effectively impossible in practice.
Je, mnapakia faili zangu kwenye seva?+
Hapana — kila zana hapa inachakata faili zako kikamilifu kwenye kifaa chako, na hakuna kinachopakiwa kwenye seva. Tofauti pekee ni zana za AI, ambazo hutuma maandishi yaliyotolewa (si faili) kwa Claude ili kufanya kazi yake.
Je, kuna kikomo cha ukubwa wa faili?+
Hatuweki kikomo cha bandia, lakini kwa kuwa uchakataji hufanyika kwenye kivinjari chako, faili kubwa sana (zaidi ya 500MB au kurasa 1,000+) hupunguzwa na kumbukumbu ya kifaa chako, si sisi.
