Lokacin da Redis aka rasa bayanai akan restart, dalilan da aka saba shine kuskuren daidaitawa Redis ko kuskuren zaɓuɓɓukan asynchronous. Redis Ainihin yana goyan bayan dagewar bayanai zuwa faifai ta amfani da Memory Snapshot(RDB) ko hanyoyin Fayil-Ƙara-kawai(AOF) don tabbatar da cewa ba a rasa bayanai ba bayan restart.
A ƙasa akwai wasu na kowa dalilai da kuma hanyoyin da za a guje wa asarar bayanai a kan Redis restart:
Injin dagewar da aka kashe
Ta hanyar tsoho, Redis baya kunna dagewar bayanai zuwa faifai. Wannan na iya haifar da asarar bayanai lokacin da kuka restart Redis. Don magance wannan batu, tabbatar da cewa kun kunna dagewar bayanai zuwa faifai ta amfani da saitunan RDB ko AOF.
Amfani da tsarin dagewa mara kyau
Idan kun kunna dagewar bayanai, tabbatar da cewa kun zaɓi hanyar dagewar da ta dace wacce ta dace da takamaiman buƙatunku. Redis yana ba da hanyoyin dagewa guda biyu, RDB da AOF. RDB tana adana bayanai azaman fayil ɗin hoto a lokaci na yau da kullun, yayin da AOF ke adana umarni waɗanda ke rataye ga bayanan. Zaɓi tsarin dagewa wanda ya dace da yanayin ku da takamaiman buƙatu.
Rashin isasshen tazara mai ɗaukar hoto
Idan kun kunna dagewar RDB, tabbatar da cewa an daidaita tazarar ɗaukar hoto daidai. Idan tazarar ɗaukar hoto ta yi tsayi da yawa, za ka iya rasa bayanai tsakanin hoton ƙarshe da Redis restart. Idan ya yi gajere sosai, zai iya yin tasiri ga aikin Redis.
Zaɓuɓɓukan asynchronous mara daidai
Idan kun kunna dagewar AOF, tabbatar da cewa an daidaita zaɓuɓɓukan asynchronous daidai. Redis yana goyan bayan zaɓuɓɓukan asynchronous kamar always, everysec da no. Zaɓin always yana tabbatar da rubutun asynchronous nan take, yayin da everysec yake rubuta asynchronously sau ɗaya a sakan daya.
Don guje wa asarar bayanai akan Redis restart, duba kuma tabbatar da cewa an saita saitunanku da kyau kuma sun daidaita tare da buƙatun aikace-aikacenku. Idan ba ku da tabbas, ƙarin koyo game da Redis daidaitawa da zaɓuɓɓukan dagewa don tabbatar da dorewar bayanai da aminci.
