Dqlite 1.0, sigar SQLite da aka rarraba daga Canonical, yana samuwa

Canonical aka buga gagarumin sakin aikin Dqlite 1.0 (Rarraba SQLite), wanda ke haɓaka injin SQL mai dacewa da SQLite wanda ke goyan bayan kwafin bayanai, dawo da kai tsaye daga faɗuwa, da haƙurin kuskure ta hanyar rarraba masu sarrafawa a kan nodes da yawa. Ana aiwatar da DBMS a cikin hanyar ɗakin karatu na C da aka haɗe zuwa aikace-aikace da rarraba ta ƙarƙashin lasisin Apache 2.0 (an bayar da asalin SQLite a cikin jama'a). Akwai ɗaurin harshe Go.

Laburaren ƙara-kan ne zuwa tushen lambar SQLite da ke akwai wanda ke ƙara goyan bayan ƙa'idar hanyar sadarwa don haɗa abubuwa da yawa na aikace-aikacen da ke gudana akan runduna daban-daban. Aikace-aikacen da aka haɗa tare da Dqlite na iya aiki azaman gungu mai jurewa kuskure mai dogaro da kansa, mai zaman kansa daga DBMSs na waje. A aikace, Canonical yana amfani da Dqlite a cikin tsarin sarrafa kwantena LXD. Daga cikin bangarorin aikace-aikacen ɗakin karatu, an kuma ambaci ƙirƙirar na'urorin Intanet masu jurewa da kurakurai da na'urori masu sarrafawa a cikin tsarin.

Don tabbatar da daidaito a cikin kwafin bayanai, ana amfani da hanyar yarjejeniya ta tushen algorithm Raft, wanda ake amfani da shi a cikin ayyuka irin su etcd, RethinkDB, CockroachDB da OpenDaylight. Dqlite yana amfani da nasa aiwatar da asynchronous C-raft, an rubuta da yaren C. Ana amfani da shirye-shiryen dakunan karatu don sarrafa haɗin haɗin kai da kuma tsara ƙaddamar da coroutines libuv и libco.
