> Hi, I read activemq kahadb soruce code. I find two problems as below:
> # Only lfu cache evict policy was provided. If we can provide more cache
> evict policy here, such as lru lruk? As we all known, there are a lot of
> cache ecict policy.
> # Lfu policy provided in source code is not prefect. You can think if the
> hot data cached in it first, but after that, hot data was never visited or
> quered, they can’t be evicted. Or some not very hot data visited, but because
> they are not very hot like hot data, as a result, some of cache was occupied
> by hot data. In other world, the cache was not very effective in this
> situation.
> Thanks.
