13. WSO2 Carbon 4.3 - New Features
oCarbon Clustering stabilization improvements
oSVN-based Deployment Synchronizer improvements
oPluggable log providers for LogViewer UI
oTenant deletion support
oUsing Java Security Manager with Carbon multi-tenancy
oCApp and artifact ghost deployment improvements
oGlobal cluster cache invalidation on remote Greg mounts

14. Carbon 4.3 - Carbon Clustering
improvements
oDistributed caching and clustering with Enterprise-grade software, Hazelcast.
oIntroduced with Carbon 4.2
oUpgraded to Hazelcast version - 3.2.6
oStabilization
“... the WSO2 Carbon core adds new distributed caching and
clustering implementations that are based on Hazelcast...
Hazelcast combines distributed data structures, distributed
caching capabilities, elasticity, memcache support, and
integration with Spring and Hibernate. These capabilities
bring several benefits to enterprise deployments, including
the ability to handle thousands of operations per second,
prevent the loss of data after crashes, and dynamically
scale as new servers are added.“ - Hazelcast

15. Carbon 4.3 - Deployment Synchronizer
oVastly improved SVN-based Deployment Synchronizer support
oNow supports Subversion 1.7 and 1.8 as the working copy format
oStabilization, and improved recovery from intermittent failures

16. Artifact/Deployment Synchronization

17. Carbon 4.3 - Pluggable Log Providers for
LogViewer UI
oThe log view ui -

18. Carbon 4.3 - Pluggable Log Providers for
LogViewer UI
oView logs from several log storages
oFile system / In memory log appender
oCassandra as a log storage
oAn SQL Server as a log storage
oA Centralized Log Viewer across the cluster
oDownload archived logs

19. Add a new Log Provider
oTo view logs from a custom log storage, say, Cassandra.
oImplement the interface org.wso2.carbon.logging.service.provider.api.
LogProvider
oRegister it as a log provider via $CARBON_HOME/repository/conf/etc/logging-
config.xml

<loggingConfig xmlns="http://wso2.org/projects/carbon/carbon.xml">
<!-- Default log provider -->
<logProviderConfig class="org.wso2.carbon.logging.service.provider.InMemoryLogProvider">
<properties/>
</logProviderConfig>

<!-- Default log file provider -->
<logFileProviderConfig class="org.wso2.carbon.logging.service.provider.FileLogProvider">
<properties/>
</logFileProviderConfig>
</loggingConfig>

20. Add a new Log File Provider
oTo download archived logs from a custom log storage, say, Cassandra.
oImplement the interface org.wso2.carbon.logging.service.provider.api.
LogFileProvider
oRegister it as a log provider via $CARBON_HOME/repository/conf/etc/logging-
config.xml

<loggingConfig xmlns="http://wso2.org/projects/carbon/carbon.xml">
<!-- Default log provider -->
<logProviderConfig class="org.wso2.carbon.logging.service.provider.InMemoryLogProvider">
<properties/>
