MIME-Version: 1.0 Content-Type: text/plain;charset="UTF-8" Content-Transfer-Encoding: 7bit xOriginalSenderIP: 151.20.187.102 X-Virus-Checked: Checked by ClamAV on apache.org Hi, I have a question about JCS behavior. Suppose this scenario: - four JCS server: S1,S2,S3,S4 - for every server a max of 10,000 cacheable objects - a client C1 I need that client C1 writes 40,000 objects to 4 JCS servers. JCS could automatic balance the objects insertion between the 4 servers partitioning the objects set (via round robin, for example)? I need the maximum performance (availability), not affordability. Substantially I need that an object instance "O1" is allocated _only_ in one server and that the client lookup is executed in parallel on the four servers. Is this possible with JCS?
