-----------------------------------
Summary: Encode ZNode names to reduce ZooKeeper jute buffer length
requirements and thus reduce memory usage
Key: HBASE-18396
URL: https://issues.apache.org/jira/browse/HBASE-18396
Project: HBase
Issue Type: Improvement
Affects Versions: 3.0.0
Reporter: Karan Mehta
In our production environment, we hit the error {{ZooKeeper connectionLoss due
to jute.maxbuffer len of 1M getting exceeded}}. Usually 1 MB is a lot, but in
case of multi requests, it can exceed the maximum buffer length that is
allocated.
This JIRA is a discussion for encoding various znode names. IMO, this will
reduce the path lengths, thus reducing the size of buffer required as well as
network packet size and also pack more requests in a single multi. As with
encoding, this will introduce overhead, but we need to determine how feasible
this idea is.
