A fost lansat primul release al sistemului de caching \u00een memorie Dragonfly, care suport\u0103 protocoalele Memcached \u0219i Redis, dar permite efectuarea de interog\u0103ri cu mult mai mult\u0103 performan\u021b\u0103 \u0219i cu un consum mai mic de memorie. Sistemul manipuleaz\u0103 datele \u00een format cheie\/valoare \u0219i poate fi aplicat ca o solu\u021bie u\u0219oar\u0103 pentru accelerarea func\u021bion\u0103rii site-urilor cu trafic intens, cache-uind interog\u0103rile lente c\u0103tre SGBD \u0219i datele intermediare \u00een memorie. Codul Dragonfly este scris \u00een limbajele C\/C++ \u0219i este distribuit sub licen\u021ba BSL (Business Source License). <\/p>\n

Licen\u021ba BSL a fost propus\u0103 de co-fondatorii MySQL ca o alternativ\u0103 la modelul Open Core. Esen\u021ba BSL este c\u0103 codul func\u021bionalit\u0103\u021bii extinse este disponibil pentru modific\u0103ri de la \u00eenceput, dar pentru o anumit\u0103 perioad\u0103 poate fi utilizat gratuit doar cu respectarea unor condi\u021bii suplimentare, altele dec\u00e2t care necesit\u0103 achizi\u021bionarea unei licen\u021be comerciale. Condi\u021biile suplimentare de licen\u021biere ale proiectului Dragonfly prev\u0103d c\u0103 traducerea codului pe licen\u021ba Apache 2.0 se va face doar pe 1 iunie 2027. P\u00e2n\u0103 atunci, licen\u021ba permite utilizarea codului doar pentru furnizarea propriilor servicii \u0219i produse, dar interzice aplicarea acestuia pentru crearea de servicii cloud pl\u0103tite care s\u0103 se ridice deasupra Dragonfly. <\/p>\n

Conform dezvoltatorilor \u0219i testelor demonstrate, Dragonfly pretinde titlul de cea mai rapid\u0103 sistem de stocare \u00een memorie. Comparativ cu Redis, \u00een Dragonfly, \u00een condi\u021bii tipice de sarcin\u0103, s-a reu\u0219it o cre\u0219tere de 25 de ori a performan\u021bei \u0219i o reducere de trei ori a consumului de memorie. Un serverul<\/a> Dragonfly poate procesa milioane de interog\u0103ri pe secund\u0103, de exemplu, \u00een mediu Amazon EC2 c6gn.16xlarge s-a ob\u021binut o performan\u021b\u0103 de 3.8 milioane de interog\u0103ri pe secund\u0103.

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

\u00cen testele de stocare a 5 GB de date, Dragonfly a solicitat cu 30% mai pu\u021bin\u0103 memorie dec\u00e2t Redis. \u00cen timpul cre\u0103rii instantaneelor cu comanda «bgsave», consumul de memorie cre\u0219te, dar \u00een momentele de v\u00e2rf r\u0103m\u00e2ne de aproape trei ori mai mic dec\u00e2t \u00een Redis, iar opera\u021biunea de scriere a instantaneului se efectueaz\u0103 semnificativ mai rapid (\u00een test, instantaneul \u00een Dragonfly a fost salvat \u00een 30 de secunde, \u00een timp ce \u00een Redis a durat 42 de secunde).

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

Performan\u021ba \u00eenalt\u0103 este ob\u021binut\u0103 gra\u021bie arhitecturii multi-thread f\u0103r\u0103 partajarea resurselor (shared-nothing), care implic\u0103 faptul c\u0103 fiec\u0103rui fir \u00eei este alocat un handler individual de date, care func\u021bioneaz\u0103 f\u0103r\u0103 mutex-uri \u0219i blocaje spin. Pentru a asigura atomicitatea proces\u0103rii cu mai multe chei, se utilizeaz\u0103 bloc\u0103ri u\u0219oare VLL. Pentru stocarea eficient\u0103 a informa\u021biei \u00een memorie, se aplic\u0103 structura dashtable, care implementeaz\u0103 o variant\u0103 de tabele hash sec\u021bionate. <\/p>\n

Printre func\u021bionalit\u0103\u021bile disponibile \u00een prima versiune se num\u0103r\u0103 suportul pentru protocolul RESP2 \u0219i 130 de comenzi Redis, ceea ce corespunde, aproximativ, func\u021bionalit\u0103\u021bii versiunii Redis 2.8. \u00cen plus, Dragonfly suport\u0103 toate comenzile memcached, cu excep\u021bia CAS (check-and-set), ofer\u0103 suport pentru opera\u021biuni asincrone pentru crearea de snapshot-uri, asigur\u0103 un consum de memorie previzibil, dispune de un interpret Lua 5.4 \u00eencorporat \u0219i suport\u0103 tipuri de date complexe, cum ar fi hash-uri, mul\u021bimi \u0219i liste (ZSET, HSET, LIST, SETS \u0219i STRING). <\/p>\n

Exist\u0103 un mod de cache disponibil, \u00een care se asigur\u0103 automat \u00eenlocuirea datelor vechi cu altele noi dup\u0103 ce memoria liber\u0103 s-a epuizat. Este posibil\u0103 legarea de date cu o durat\u0103 de via\u021b\u0103, pe durata c\u0103reia datele sunt considerate actuale. Starea stoc\u0103rii poate fi salvat\u0103 pe disc \u00een fundal pentru o recuperare ulterioar\u0103 dup\u0103 repornire. Pentru gestionarea sistemului este disponibil\u0103 o consol\u0103 HTTP (legat\u0103 de portul TCP 6379) \u0219i un API pentru livrarea metricilor, compatibil cu Prometheus. \u00cen versiunile urm\u0103toare, se preconizeaz\u0103 extinderea suportului pentru comenzile Redis \u0219i implementarea capacit\u0103\u021bii de replicare a stoc\u0103rii pentru asigurarea redundan\u021bei \u0219i a echilibr\u0103rii \u00eenc\u0103rc\u0103rii.
