> Key: OAK-11182
> URL: https://issues.apache.org/jira/browse/OAK-11182
> Project: Jackrabbit Oak
> Issue Type: Task
> Components: mongomk
> Reporter: Horia Poradici
> Assignee: Rishabh Daim
> Priority: Major
> Fix For: 1.74.0
>
>
> The purpose of this ticket is to create methods for generating garbage that
> can be collected as part of testing fullGC.
> A new Command class in oak-run should be used for this, with parameters for
> adjusting how garbage should be generated.
> The methods used in VersionGarbageCollectorIT.java for generating garbage can
> be used as inspiration and/or starting point.
> The usage of these methods will be to run them on the MongoDB of the stage
> environment that we are currently testing on, and to check how fullGC
> continuously collecting the garbage affects performance of the Author pods.
>
> *Definition of Done:*
> Methods are created for doing the following:
> 1. Generate *1.000+* fullGC garbage (of type EMPTY_PROPERTIES) under a
> *single* node.
> 2. Generate *10.000+* fullGC garbage (of type GAP_ORPHANS or
> EMPTY_PROPERTIES) under *multiple* nodes.
> 3. Generate *50.000+* fullGC garbage of type GAP_ORPHANS (in total) under
> *1.000+* nodes.
> 4. Generate *200.000+* fullGC garbage of type GAP_ORPHANS (in total) under
> *10.000+* nodes.
> The methods should allow for generation of garbage on {*}any MongoDB
> database{*}, specified by connection string.
> The methods should be as general as possible, with parameters for the number
> of:
> * total fullGC garbage nodes to create
> * the total number of nodes under which to create garbage
> * the type of garbage to create: at least EMPTY_PROPERTIES and GAP_ORPHANS
> should be supported, with the possibility of adding more in the future.
> * *delays* for generating garbage repeatedly, as well as {*}number of
> repeated runs{*}, so the method can be started and it should run for an
> indefinite period of time
> * the *modified* timestamp for the created nodes, so that garbage with any
> *age* can be generated
