The RespectChildFullness configuration option instructs the DIH to stop indexing documents into a child server that reports that it is full. You can configure the MaxDocumentCount for the child servers to specify when a child server must report that it is full.
If you are using RespectChildFullness, you can also limit indexing to a specified number of configured child server groups, by setting the RespectChildFullnessMaxIndexingGroups configuration parameter. In this mode, DIH indexes to the first N server groups, where N is the value of RespectChildFullnessMaxIndexingGroups. As the server groups become full, DIH indexes to the least full server groups, but to a maximum of N at a time. You might want to use this option if you want to limit the total I/O for your system, if the child servers share capacity.
