33 ## - 3904 is standard as of 7/29/14.
34 ## - At this time, Cambria always binds to 0.0.0.0

43 ## The Cambria server can run either as a memory-only implementation, meant
44 ## for testing, or against Kafka. For a memory-only server, use "memory" for
45 ## the broker.type setting.

51 ## Zookeeper Connection
53 ## Both Cambria and Kafka make use of Zookeeper.

64 ## configurations (after removing "kafka.")

73 ## Some data stored in the config system is sensitive -- API keys and secrets,
74 ## for example. to protect it, we use an encryption layer for this section
77 ## The key is a base64 encode AES key. This must be created/configured for
79 #cambria.secureConfig.key=
81 ## The initialization vector is a 16 byte value specific to the secured store.

97 ## Kafka expects live connections from the consumer to the broker, which
98 ## obviously doesn't work over connectionless HTTP requests. The Cambria
99 ## server proxies HTTP requests into Kafka consumer sessions that are kept
100 ## around for later re-use. Not doing so is costly for setup per request,
101 ## which would substantially impact a high volume consumer's performance.
103 ## This complicates Cambria server failover, because we often need server
104 ## A to close its connection before server B brings up the replacement.
107 ## The consumer cache is normally enabled.
108 #cambria.consumer.cache.enabled=true
110 ## Cached consumers are cleaned up after a period of disuse. The server inspects
111 ## consumers every sweepFreqSeconds and will clean up any connections that are
112 ## dormant for touchFreqMs.
113 #cambria.consumer.cache.sweepFreqSeconds=15
114 #cambria.consumer.cache.touchFreqMs=120000
116 ## The cache is managed through ZK. The default value for the ZK connection
117 ## string is the same as config.zk.servers.
118 #cambria.consumer.cache.zkConnect=${config.zk.servers}
121 ## Shared cache information is associated with this node's name. The default
122 ## name is the hostname plus the HTTP service port this host runs on. (The
123 ## hostname is determined via InetAddress.getLocalHost ().getCanonicalHostName(),
124 ## which is not always adequate.) You can set this value explicitly here.
126 #cambria.api.node.identifier=<use-something-unique-to-this-instance>
