Why is table distribution necessary?
Tables are distributed among the available hosts to provide the necessary load balance.
In case you experience an OOM situation happening on one particular host within your landscape then it needs to be investigated if the load is properly distributed among all the available hosts.
Two kinds of scenarios are available for SAP HANA: Scale-up and Scale-out solution.
Scale-up means to use powerful single server to process the workload that fits within the server boundaries.
Scale-out is a different model which utilizes multiple processors as a single entity so a business can scale beyond the computer capacity of a single server. Table distribution is possible only in Scale-out scenario.
