----------------------------------
Summary: Netty based TCP broadcasting cache
Key: OAK-3950
URL: https://issues.apache.org/jira/browse/OAK-3950
Project: Jackrabbit Oak
Issue Type: New Feature
Components: cache
Reporter: Philipp Suter
The attached patch introduces netty 4 [1] based tcp broadcasting for the
broadcasting feature of the persistent cache.
It adds an additional configuration option for the broadcasting cache:
nettyTcp. The configuration works similar to the tcp configuration. In addition
unsafe SSL can be configured with "ssl true".
The code expects netty to be installed once it is instantiated. Broadcasting
cache should also run without netty being available. As long as nettyTcp is not
configured.
Dev testing has shown some improvements in regard of performance.
Known areas:
- Threading: Netty uses lots of threads. This might impact overall performance
of OAK and would have to be tested. Threads are currently limited to a
hardcoded max number.
- Configuration: Some areas should be configurable.
- SSL: can be configured by setting "ssl true" in the nettyTcp configuration.
It is currently only for development purposes as it accepts all certificates.
