Essa separa\u00e7\u00e3o reduz a superf\u00edcie de ataque do n\u00facleo do Valkey e permite que os administradores desativem completamente o Lua, caso os scripts n\u00e3o estejam sendo usados. Para facilitar a compreens\u00e3o dos motores de scripts carregados no sistema, o comando INFO recebeu uma nova se\u00e7\u00e3o na resposta \u2014 Scripting Engines.<\/p>\n<\/li>\n<li>\n<p><strong>Novas corre\u00e7\u00f5es de seguran\u00e7a.<\/strong><br \/>\nA vers\u00e3o est\u00e1vel 9.1.0 inclui corre\u00e7\u00f5es para tr\u00eas vulnerabilidades: uso ap\u00f3s libera\u00e7\u00e3o no mecanismo de desbloqueio do cliente, acesso incorreto \u00e0 mem\u00f3ria no comando 7RESTORE, bem como uso ap\u00f3s libera\u00e7\u00e3o durante a sincroniza\u00e7\u00e3o completa ao executar c\u00f3digo Lua\/function com ced\u00eancia de execu\u00e7\u00e3o. Elas s\u00e3o referidas nas notas como CVE-2026-23479, CVE-2026-25243 e CVE-2026-23631.<\/p>\n<\/li>\n<li>\n<p><strong>ACL a n\u00edvel de banco de dados.<\/strong><br \/>\nFoi adicionada uma sistema de controle de acesso a n\u00edvel de bancos de dados individuais. Isso permite uma pr\u00e9via mais fina dos direitos em configura\u00e7\u00f5es multiusu\u00e1rio e n\u00e3o se restringe apenas \u00e0s regras de acesso globais a n\u00edvel de toda a inst\u00e2ncia do Valkey.<\/p>\n<\/li>\n<li>\n<p><strong>Recarregamento autom\u00e1tico de certificados TLS.<\/strong><br \/>\nO Valkey 9.1 recebeu suporte para recarregamento autom\u00e1tico de certificados TLS. Para administradores, isso significa menos opera\u00e7\u00f5es manuais na rota\u00e7\u00e3o de certificados e uma opera\u00e7\u00e3o mais conveniente de implanta\u00e7\u00f5es seguras.<\/p>\n<\/li>\n<li>\n<p><strong>Novo comando HGETDEL.<\/strong><br \/>\nO comando obt\u00e9m e remove de forma at\u00f4mica um ou mais campos de uma estrutura hash. O significado pr\u00e1tico \u2014 scripts semelhantes a filas ou consumo \u00fanico de dados, onde anteriormente era necess\u00e1rio combinar HGET e HDEL por meio de uma transa\u00e7\u00e3o.<\/p>\n<\/li>\n<li>\n<p><strong>Nova equipe MSETEX.<\/strong><br \/>\nO MSETEX permite definir m\u00faltiplas chaves com um \u00fanico tempo de vida. Anteriormente, esse cen\u00e1rio exigia m\u00faltiplas chamadas SETEX ou uma combina\u00e7\u00e3o de SET e EXPIRE atrav\u00e9s de um pipeline. A nova equipe reduz o n\u00famero de chamadas e simplifica o c\u00f3digo t\u00edpico para dados de sess\u00e3o e tempor\u00e1rios.<\/p>\n<\/li>\n<li>\n<p><strong>Nova equipe CLUSTERSCAN.<\/strong><br \/>\nNos clusters, h\u00e1 uma \u00fanica equipe para escanear chaves em todos os n\u00f3s. Antes, os clientes precisavam executar SCAN em cada n\u00f3 e combinar os resultados. O CLUSTERSCAN simplifica bibliotecas de cliente, ferramentas administrativas e tarefas operacionais, como a busca de chaves por padr\u00e3o ou tipo em todo o cluster.<\/p>\n<\/li>\n<li>\n<p><strong>Otimiza\u00e7\u00e3o do consumo de mem\u00f3ria por strings.<\/strong><br \/>\nGra\u00e7as a otimiza\u00e7\u00f5es internas de ponteiros para strings menores que 128 bytes, foi relatada uma redu\u00e7\u00e3o no consumo de mem\u00f3ria de at\u00e9 20%. Isso \u00e9 especialmente importante para cargas t\u00edpicas de cache, onde um grande n\u00famero de pequenos valores \u00e9 armazenado.<\/p>\n<\/li>\n<li>\n<p><strong>Menos mem\u00f3ria para conjuntos ordenados.<\/strong><br \/>\nOtimiza\u00e7\u00f5es nas estruturas de skiplist reduzem o uso de mem\u00f3ria para conjuntos ordenados em at\u00e9 10%. Al\u00e9m disso, as opera\u00e7\u00f5es em conjuntos ordenados foram aceleradas, incluindo consultas como ZRANGEBYSCORE e ZRANGEBYLEX.<\/p>\n<\/li>\n<li>\n<p><strong>Trabalho acelerado com rehashing.<\/strong><br \/>\nA redistribui\u00e7\u00e3o interna das tabelas hash, que geralmente ocorre com o crescimento do keyspace, foi otimizada para reduzir a lat\u00eancia. As notas de lan\u00e7amento tamb\u00e9m mencionam a diminui\u00e7\u00e3o de picos de lat\u00eancia devido \u00e0 libera\u00e7\u00e3o de p\u00e1ginas incremental.<\/p>\n<\/li>\n<li>\n<p><strong>Modelo de I\/O threading aprimorado.<\/strong><br \/>\nNa vers\u00e3o candidato 9.1.0-rc2, foi reformulado o modelo de intera\u00e7\u00e3o dos threads de entrada e sa\u00edda usando filas sem bloqueio. Nas notas, foi mencionado um aumento na capacidade de 8-17%.<\/p>\n<\/li>\n<li>\n<p><strong>Acelera\u00e7\u00e3o de GET e SET.<\/strong><br \/>\nO Valkey agora usa por padr\u00e3o rel\u00f3gios de hardware onde poss\u00edvel, reduzindo a sobrecarga de chamadas de sistema relacionadas ao tempo. O projeto relata um aumento de desempenho de GET e SET de at\u00e9 3% no geral.<\/p>\n<\/li>\n<li>\n<p><strong>Exclus\u00f5es em massa mais r\u00e1pidas.<\/strong><br \/>\nDurante opera\u00e7\u00f5es como SREM, ZREM e HDEL, o Valkey agora suspende temporariamente a mudan\u00e7a do tamanho das tabelas hash para evitar rehashing desnecess\u00e1rio e acelerar a exclus\u00e3o em massa de elementos.<\/p>\n<\/li>\n<li>\n<p><strong>Cria\u00e7\u00e3o de r\u00e9plicas mais eficiente com AOF.<\/strong><br \/>\nAo criar uma r\u00e9plica com AOF ativado, agora \u00e9 reutilizado o arquivo RDB gerado em vez de gerar uma nova captura para o arquivo base AOF. Isso deve reduzir a carga desnecess\u00e1ria ao implantar r\u00e9plicas.<\/p>\n<\/li>\n<li>\n<p><strong>Melhorias no valkey-cli e valkey-benchmark.<\/strong><br \/>\nNo valkey-cli foi adicionada a suportar a migra\u00e7\u00e3o de slot at\u00f4mico atrav\u00e9s do par\u00e2metro \u2014cluster-use-atomic-slot-migration para as opera\u00e7\u00f5es \u2014cluster rebalance e \u2014cluster reshard. No valkey-benchmark, foi adicionado a sa\u00edda da distribui\u00e7\u00e3o RPS, assim como os par\u00e2metros \u2014warmup e \u2014duration, tornando o teste de desempenho mais
