scrapy-redis的集群版,可以借助Redis集群实现海量网站的独立去重,避免单机内存不足的尴尬
它依赖redis-py-cluster
StrictRedisCluster 改名字了
您好,我是个新手,我在运行的时候总是出现这个问题
File "c:\users\sdd\appdata\local\programs\python\python36\lib\site-packages\rediscluster\nodemanager.py", line 12, in
from redis._compat import b, unicode, bytes, long, basestring
ImportError: cannot import name 'b'
您能帮忙看看怎么回事吗,谢谢
使用这个组件我是需要先搭建一套redis集群嘛?
当BLOOMFILTER_BIT设置为30时, 起不到去重效果。
> fp = '75d6587d87b3f4f3aa574b33dbd69ceeb9eafe7b'
> bf = BloomFilter(server, 'ldy4', 30, 6)
> bf.exists(fp)
0
> bf.insert(fp)
> bf.exists(fp)
0
当BLOOMFILTER_BIT 设置为22时没有问题, 不知道是什么原因
这个是用来解决redis内存占用空间过大的问题吗?
使用多台redis机器代替单台?
scrapy-redis-cluster如果redis集群有密码,该如何配置?
