Projekti kood on kirjutatud Go keeles (klienditeeki Java keeles) ja jagatakse Apache 2.0 litsentsi alusel. Edasises arenduses v\u00f5etakse kogukonna parandusi, t\u00e4iustusi ja muudatusi arvesse. <\/p>\n

JunoDB arhitektuur p\u00f5hineb koormuse tasakaalustajal, mis v\u00f5tab vastu p\u00e4ringud kliendirakendustelt ja jagab need edasi vaheserveritele, mis samal ajal p\u00f6\u00f6rdudes andmebaasi r\u00fchma poole serverite<\/a> p\u00e4ringu t\u00e4itmise ajal. Iga vaheserver loob \u00fchenduse k\u00f5igi serveritega<\/a> and redirects requests to the storage server group based on a partitioning index, which is stored in a distributed storage configuration system called etcd.

\"PayPal<\/center> <\/p>\n

Data is partitioned and mapped to storage nodes using hashing, which reduces data movement when nodes in the cluster are added or removed. To ensure fault tolerance, each portion of data is replicated across multiple storage nodes, preserving information in the event of individual server failures. Territorially distributed storages are supported, where groups of nodes are located in different data centers.

\"PayPal<\/center> <\/p>\n

On storage nodes, data is placed in memory or in local storage based on the RocksDB library. For persistent storage, data is stored in an encrypted format (the encryption key can be defined by either the client or set at the proxy level).

\"PayPal<\/center> <\/p>\n

Andmebaasi juurdep\u00e4\u00e4suks saadetakse rakendustele kliendiraamatukogu, mis pakub API-d Java, Go ja C++ keelte rakendustele. Kliendi osa on maksimaalselt lihtsustatud ning keeruline loogika ja seadistused on v\u00f5imalusel viidud andmebaasi poolele. Kliendi ja tasakaalustaja v\u00f5i proksi vaheline suhtlemine toimub kr\u00fcpteeritud suhtluskanali kaudu. Juhtimiseks ja p\u00e4ringute saatmiseks saab kasutada k\u00e4surealiidest, mis katab kogu kliendi API v\u00f5imalused. <\/p>\n

S\u00fcsteem on projekteeritud t\u00f6\u00f6tlema p\u00e4ringuid ettearvatavate madalate viivitustega; n\u00e4iteks kolmepoolne salvestuskluster ja \u00fcks proksi, mis on moodustatud n1-highmem-32 (32 CPU Intel Xeon 2.30GHz, 214G RAM ja 450G SSD-p\u00f5hine salvestus) keskkondadest, suutis pakkuda fikseeritud viivitusi, mis ei \u00fcletanud 2,5 ms 95% juhtudest ja 16 ms 99% juhtudest 200 000 samaaegse TLS-\u00fchenduse ja 15 000 p\u00e4ringu kohta sekundis (3000 samaaegse \u00fchenduse ja 80 000 p\u00e4ringu mahu korral ei \u00fcletanud viivitused 6 ms 95% juhtudest ja 15 ms 99% juhtudest). PayPalis teenindavad JunoDB baasil teenused umbes 350 miljardit p\u00e4ringut p\u00e4evas.
