Variável de fluxo de mule versus desempenho de variável de sessão

Question

Além das diferenças de funcionalidade entre a variável de fluxo e a variável de sessão, conforme descrito na página Mulesoft, há alguma diferença significativa de desempenho a ser observada ao usar as duas?

Para o meu projeto, usar variáveis ​​de fluxo e sessão funciona perfeitamente bem.Portanto, preciso decidir qual usar.

Answer 1

As variáveis de sessão são constantemente serializadas e desserializadas quando as mensagens cruzam as fronteiras de transporte.

Mas, você está dizendo que você pode usar variáveis de fluxo ou sessão de forma intercambiável em seu projeto, então significa que você não tem nenhum limite de transporte (caso contrário, você perderia as variáveis de fluxo).

Nesse caso, ambas as variáveis de fluxo e sessão executam o mesmo: são apenas propriedades do evento.

Observe que as variáveis da sessão tendem a vazar por meio de endpoints http, então tenha cuidado com o uso.
