Package org.infinispan.hotrod.configuration

package org.infinispan.hotrod.configuration
Hot Rod client configuration API.

It is possible to configure the

invalid reference 
org.infinispan.hotrod.RemoteCacheManager
either programmatically, using a URI or by constructing a HotRodConfiguration using a HotRodConfigurationBuilder or declaratively, by placing a properties file named hotrod-client.properties in the classpath.

A Hot Rod URI follows the following format: hotrod[s]://[user[:password]@]host[:port][,host2[:port]][?property=value[&property2=value2]]

  • hotrod or hotrods specifies whether to use a plain connection or TLS/SSL encryption.
  • user and password optionally specify authentication credentials.
  • host and port comma-separated list of one or more servers.
  • property and value one or more ampersand-separated (&) property name/value pairs. The property name must omit the infinispan.client.hotrod prefix.

The following table describes the individual properties and the related programmatic configuration API.

If the TTL of the DNS resource record returned by the DNS server is longer than the maximum TTL, the resolver ignores the TTL provided by the DNS server and uses the maximum TTL instead. The defaults respect the DNS server TTL.
