> Rebalancing/Redundancy will refuse to create or move a bucket to a node if that node will go over the configured local-max-memory setting, but only if eviction is not enabled for the region. This is because if eviction is enabled the region is not limited to the in memory size.
> However, PartitionRegionRebalanceOp.buildModel is only looking at the leader region in a set of colocated regions when deciding to enforce local-max-memory
> {code}
> boolean enforceLocalMaxMemory = !leaderRegion.isEntryEvictionPossible();
> {code}
> This means that if there is a parent region without eviction and colocated regions that do have eviction enabled, all those regions will enforce this constraint.
> The check on whether to enforce this constraint should be applied on a region-by-region basis. The PartitionRegionLoadModel is already tracking the size and local-max-memory for each colocated region, so it should be able to decide whether to check the constraint for each colocated region.
