Outbox pattern muammoning faqat yarmini hal qiladi Yaxshi, xabaringiz bazadan chiqib ketdi. Ammo consumer tomonida nima bo'layapti? Ana shu joyni ko'pchilik unutadi. Outbox bir narsani kafolatlaydi: hodisa (event) biznes-tranzaksiya commit bo'lgandan keyin e'lon qilinadi. Ya'ni "pul yechildi, lekin xabar ketmadi" degan sharmandalik bo'lmaydi. Zo'r. Lekin bu hikoyaning oxiri emas. Tasavvur qiling: servis hodisani qabul qildi, uni qayta ishladi va aynan tasdiq (acknowledgement) yuborishdan bir soniya oldin yiqildi. Klassika. Endi u o'zini oqlagandek turadi-yu, brokerdan o'sha xabar yana keladi. Va yana bir marta ishlanadi. Natijada? Bir xaridordan ikki marta pul yechiladi, bitta xat o'rniga uchta ketadi, ombordagi qoldiq esa umuman o'z hayotini yashay boshlaydi. Mijoz xursand emas, buxgalter ham. Bu yerda Inbox pattern yordamga keladi. Consumer xabarning ID sini saqlab qo'yadi va biznes-operatsiyani xuddi shu bitta bazaviy tranzaksiya ichida bajaradi. Ikkovi birga: yo ikkalasi ham bo'ladi, yo hech qaysi biri. Agar o'sha xabar yana kelib qolsa, consumer uni tanib oladi — "ha, seni ko'rganman, o'tir joyingga" — va takroriy ishlashni sokingina o'tkazib yuboradi. Formula oddiy: - Outbox jo'natuvchini himoya qiladi. - Inbox qabul qiluvchini himoya qiladi. Ikkalasi birlashib, ko'pchilik taqsimlangan (distributed) tizimlarga aslida kerak bo'lgan ishonchlilik modelini beradi: Kamida bir marta yetkazish (at-least-once) + idempotent qayta ishlash. Va endi eng muhimi. Exactly-once delivery — bu ko'pincha shunchaki va'da. Chiroyli slaydlarda yaxshi ko'rinadi, prod'da esa boshqacha. Haqiqatda exactly-once'ga o'xshab ishlaydigan xatti-harakat — bu sotib oladigan xususiyat emas, bu sizning arxitekturangiz. Uni sotib olib bo'lmaydi, uni qurish kerak. @Copyright manba: Backend Portal kanali

Claude Code ishlatmoqchi bo'lganlar yoki ishlatayotganlar uchun foydali repo topib oldim. Oddiy prompt yozishdan tashqari, agentlar, hooklar, skill va MCP serverlar bilan ishlashni, ularni qanday orchestrate qilishni o'rgatadi. Repo ichida ancha ko'p vizual tutoriallar va copy-paste templatelar bor, sinab ko'rish kerak. O'zim ba'zi narsalarni shu reponi ichidan o'rganib o'tiribman https://github.com/luongnv89/claude-howto @mabrur_dev
