@PuKoren Thanks for your sharing. It's very helpful.
@PuKoren Hello, I'm so sorry to bother you again. Below is my code. Some pdf work well and faster,but some pdf got segmentation violation error and looks like non-random. I...
@PuKoren Thank you for your reply, this problem still exists, even if I use built-int func 'copy' to copy input byte slice for each goroutine. For most cases,it works fine,but...
> @xiaoxfan are those PDF working when processed without goroutines with a single gofitz instance? Yes
> @xiaoxfan If you use the same code I pasted here you get the same issue? Yes, only a few specific pdf files (5 pages,no obvious difference from the others)...

singleflight这样理解对不对： 在一瞬间有大量请求get(key)，而且key未被缓存或者未被缓存在当前节点 如果不用singleflight，那么这些请求都会发送远端节点或者从本地数据库读取，会造成远端节点或本地数据库压力猛增。使用singleflight，第一个get(key)请求到来时，singleflight会记录当前key正在被处理，后续的请求只需要等待第一个请求处理完成，取返回值即可。
