> Currently SCM maintains a list of preallocated containers and allocates blocks from these
containers. This approach does not work well with dynamics of the cluster where new nodes
are being added and pipelines are destroyed. New containers are not created until all the
preallocated containers are exhausted.
> The Jira aims to establish a criteria in block allocation where first a pipeline is selected
amongst the available pipelines and then a container is selected in that pipeline. In order
to handle the dynamics of the cluster a fixed interval pipeline creator job can be launched
which creates pipelines in the system.
