<div>- I do not want to iterate each and every key and there then decide whether its a user or a group .I could have so many users or group entries.The thing here is that I dont have the keys i need to iterate.I would want to iterate on every User entity or group entity</div> <div>Suppose I have 1000 users and 2000 groups in one cache,and if i just needed all the 1000 users, I would unnessary iterate 3000 keys.</div> <div> </div> <div>Thanks</div> <div>Abhishek<BR><BR><B><I>Steven Grimm <sgrimm@facebook.com></I></B> wrote:</div> <BLOCKQUOTE class=replbq style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #1010ff 2px solid">You can indeed set up two memcached instances on different ports.
