 xref:learn:buckets-memory-and-storage/memory.adoc#ejection[Ejection] means that documents are removed from RAM but the key and metadata remain.
 If the amount of RAM used by items reaches the high water mark (upper threshold), both active and replica data are ejected until the memory usage (amount of RAM consumed) reaches the low water mark (lower threshold).
 The server determines that items are not recently used based on a not-recently-used (NRU) value.

-*Examples for setting percentage of ejected items*
-
-Based on the NRU algorithm, the server ejects active and replica data from a node.
-By default, the server is configured to 60% active items and 40% replica data from a node.
-
-The following example increases the percentage of active items that can be ejected from a node to 50%.

-Be aware of potential performance implications when changing the percentage of ejected items.
-It may be more desirable to eject as many replica items as possible and limit the amount of active data that can be ejected.
-By doing so, active data from a source node is maximized while maintaining incoming requests to that node.
-However, if the server is ejecting a very large percentage of replica data and a node fails, the replica data is not immediately available.
-In this case, the items are retrieved from disk and put back into RAM before the request is fulfilled.
 
-The following example response shows the low water mark, high water mark, and percentage of ejected items being set.
