> ---------------------------------
>
> Key: GEODE-8295
> URL: https://issues.apache.org/jira/browse/GEODE-8295
> Project: Geode
> Issue Type: Improvement
> Components: redis
> Reporter: Darrel Schneider
> Assignee: Darrel Schneider
> Priority: Major
>
> Here are some things to do to cleanup GeodeRedisServer:
> # remove main thread from GeodeRedisServer
> # remove NamedThreadFactory in favor of geode's LoggingThreadFactory and
> LoggingExecutors
> # remove logLevel since it is configured by gemfire
> # pass an existing cache to the GeodeRedisServer constructor
> # do region creation and initialization in RegionProvider
> # extract passive expiration code
> # extract netty server code
