pika 没有实现SLOTSMGRT-EXEC-WRAPPER的读迁移功能

No response

Description

正常一个slot被标识成migrating，proxy 会把get aa 封装 成SLOTSMGRT-EXEC-WRAPPER aa get aa

里面上，pika要是存在这个key，应该返回2和aa的value。 现在pika只实现0， 1， -1 这3个返回值

导致所有读该slot的key，也得不停重试。直到该slot迁移结束。导致迁移的时候，对读不友好。

Proposed solution

建议实现SLOTSMGRT-EXEC-WRAPPER 的读迁移中的key的功能

Alternatives considered

增加slot可以降低重试
