Est\u00e1 dispon\u00edvel a primeira vers\u00e3o do sistema de cache de dados em mem\u00f3ria Dragonfly, que oferece suporte aos protocolos Memcached e Redis, mas permite realizar consultas com muito mais desempenho e menor consumo de mem\u00f3ria. O sistema manipula dados no formato chave\/valor e pode ser usado como uma solu\u00e7\u00e3o leve para acelerar o desempenho de sites de alta carga, armazenando em cache consultas lentas ao banco de dados e dados intermedi\u00e1rios na mem\u00f3ria. O c\u00f3digo do Dragonfly \u00e9 escrito em C\/C++ e \u00e9 distribu\u00eddo sob a licen\u00e7a BSL (Business Source License). <\/p>\n

A licen\u00e7a BSL foi proposta pelos cofundadores do MySQL como uma alternativa ao modelo Open Core. A ess\u00eancia da BSL \u00e9 que o c\u00f3digo da funcionalidade estendida est\u00e1 inicialmente dispon\u00edvel para modifica\u00e7\u00e3o, mas por um determinado per\u00edodo pode ser utilizado gratuitamente apenas sob certas condi\u00e7\u00f5es adicionais, para contornar as quais \u00e9 necess\u00e1ria a aquisi\u00e7\u00e3o de uma licen\u00e7a comercial. As condi\u00e7\u00f5es adicionais da licen\u00e7a do projeto Dragonfly preveem a migra\u00e7\u00e3o do c\u00f3digo para a licen\u00e7a Apache 2.0 apenas em 1\u00ba de junho de 2027. At\u00e9 esse momento, a licen\u00e7a permite o uso do c\u00f3digo apenas para garantir a opera\u00e7\u00e3o de seus servi\u00e7os e produtos, mas pro\u00edbe a aplica\u00e7\u00e3o para criar servi\u00e7os de nuvem pagos que funcionem como uma camada sobre o Dragonfly. <\/p>\n

De acordo com os desenvolvedores e os testes demonstrados, o Dragonfly se apresenta como o sistema de armazenamento em mem\u00f3ria mais r\u00e1pido. Em compara\u00e7\u00e3o com o Redis, o Dragonfly conseguiu um aumento de 25 vezes no desempenho e uma redu\u00e7\u00e3o de tr\u00eas vezes no consumo de mem\u00f3ria em tipos t\u00edpicos de carga. Um servidor<\/a> O Dragonfly pode processar milh\u00f5es de consultas por segundo; por exemplo, em um ambiente Amazon EC2 c6gn.16xlarge, foi alcan\u00e7ado um desempenho de 3,8 milh\u00f5es de consultas por segundo.

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

Nos testes de armazenamento de 5 GB de dados, o Dragonfly exigiu 30% menos mem\u00f3ria do que o Redis. Durante a cria\u00e7\u00e3o de snapshots com o comando «bgsave», o consumo de mem\u00f3ria aumenta, mas nos momentos de pico permanece quase tr\u00eas vezes menor do que no Redis, e a pr\u00f3pria opera\u00e7\u00e3o de grava\u00e7\u00e3o do snapshot \u00e9 realizada significativamente mais r\u00e1pido (no teste, o snapshot no Dragonfly foi gravado em 30 segundos, enquanto no Redis — em 42 segundos).

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

Desempenho elevado \u00e9 alcan\u00e7ado gra\u00e7as \u00e0 arquitetura multithreaded sem compartilhamento de recursos (shared-nothing), que implica a vincula\u00e7\u00e3o de um manipulador isolado a cada thread, cada um com sua pr\u00f3pria por\u00e7\u00e3o de dados, operando sem mutexes e bloqueios spin. Para garantir a atomicidade ao trabalhar com v\u00e1rias chaves, s\u00e3o utilizadas bloqueios leves VLL. Para o armazenamento eficiente de informa\u00e7\u00f5es na mem\u00f3ria, \u00e9 utilizada a estrutura dashtable, implementando uma variante de tabelas hash particionadas. <\/p>\n

Entre as funcionalidades dispon\u00edveis na primeira vers\u00e3o, destaca-se o suporte ao protocolo RESP2 e a 130 comandos do Redis, o que corresponde aproximadamente \u00e0 funcionalidade da vers\u00e3o Redis 2.8. Al\u00e9m disso, o Dragonfly suporta todos os comandos do memcached, exceto o CAS (check-and-set), fornece suporte a opera\u00e7\u00f5es ass\u00edncronas para cria\u00e7\u00e3o de snapshots, garante um consumo de mem\u00f3ria previs\u00edvel, oferece um interpretador Lua 5.4 embutido e suporta tipos de dados complexos, como hashes, conjuntos e listas (ZSET, HSET, LIST, SETS e STRING). <\/p>\n

Um modo de cache separado est\u00e1 dispon\u00edvel, onde os dados antigos s\u00e3o automaticamente substitu\u00eddos por novos ap\u00f3s o esgotamento da mem\u00f3ria livre. \u00c9 poss\u00edvel vincular um tempo de vida aos dados, durante o qual eles s\u00e3o considerados v\u00e1lidos. O estado do armazenamento pode ser despejado em disco em segundo plano para posterior recupera\u00e7\u00e3o ap\u00f3s reinicializa\u00e7\u00e3o. Para gerenciar o sistema, uma console HTTP \u00e9 fornecida (vinculada \u00e0 porta TCP 6379) e uma API para entrega de m\u00e9tricas, compat\u00edvel com Prometheus. Vers\u00f5es futuras planejam expandir o suporte aos comandos do Redis e implementar a capacidade de replica\u00e7\u00e3o do armazenamento para garantir toler\u00e2ncia a falhas e balanceamento de carga.
