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.
