Hi All, I was going through Curator as a Zookeeper java library. It is looking promising. Though to take your guidance to see if it is good to use any library or just stick with basic API provided by Zookeeper. Following is summary of benefiet of using Curator
Curator deals with ZooKeeper complexity in the following ways: Retry Mechanism: Curator supports a pluggable retry mechanism. All ZooKeeper operations that generate a recoverable error get retried per the configured retry policy. Curator comes bundled with several standard retry policies (e.g. exponential backoff). Connection State Monitoring: Curator constantly monitors the ZooKeeper connection. Curator users can listen for state changes in the connection and respond accordingly. ZooKeeper Instance Management: Curator manages the actual connection to the ZooKeeper cluster using the standard ZooKeeper class. However, the instance is managed internally (though you can access it if needed) and recreated as needed. Thus, Curator provides a reliable handle to the ZooKeeper cluster (unlike the built-in implementation). Correct, Reliable Recipes: Curator comes bundled with implementations of most of the important ZooKeeper recipes (and some additional recipes as well). The implementations are written using ZooKeeper best practices and take account of all known edge cases (as mentioned above). Curator's focus on recipes makes your code more resilient as you can focus strictly on the ZooKeeper feature you're interested in without worrying about correctly implementing ZooKeeper housekeeping requirements. Please advice.
