Another High Perofrmance Redis Proxy, Replacement of Twemproxy

onecache's Issues

Backend mark down by the timeout setting.

When we config a timeout value at Redis side, the OneCache will mark it down for every timeout period.

So please adjust the timeout value to 0 to disable it, because OneCache will keep a connection pool with Redis instance.

We will improve it soon.

pid file required for admin scripts.

Suggest to add a pid file.

m_threadPoolRefCount可能栈溢出

在redisproxy.cpp 318行中

EventLoopThread* loopThread = m_eventLoopThreadPool->thread(m_threadPoolRefCount % threadCount);
++m_threadPoolRefCount;

m_threadPoolRefCount初始化为 unsigned int m_threadPoolRefCount; 如果大量的请求将会导致m_threadPoolRefCount超过unsigned int的最大值从而导致值异常程序崩溃

make in Ubuntu

modify Makefile the next contents:

/usr/local/lib ------> /usr/lib/x86_64-linux-gnu

LIBS     = $(SUBLIBS)  /usr/lib/x86_64-linux-gnu/libevent.a /usr/lib/x86_64-linux-gnu/libevent_pthreads.a -lrt -pthread /usr/lib/x86_64-linux-gnu/libjemalloc
.a

hot key cache for better performance

A hot key cache can be implented to fasten the QPS greately, after we get top keys from statistics, we could ask OneCache to cache the values, then next access can be served from OneCache directly.

Remove unnecessary null pointer checks

An extra null pointer check is not needed in functions like the following.

• CTopKeySorter
• Vector::clear

Question: Writing to multiple masters

Can Onecache be configured to write to two or more masters? May be using pipepine to replicate on 2nd master.
