# RespectChildFullness

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.
