Class IndexStorageOptimizationListener

java.lang.Object

ca.uhn.fhir.jpa.model.listener.IndexStorageOptimizationListener

public class IndexStorageOptimizationListener
extends Object

Sets SP_NAME, RES_TYPE, SP_UPDATED column values to null for all HFJ_SPIDX tables if storage setting StorageSettings.isIndexStorageOptimized() is enabled.

Using EntityListener to change HFJ_SPIDX column values right before insert/update to database.

As SP_NAME, RES_TYPE values could still be used after merge/persist to database, we are restoring them from HASH_IDENTITY value.

See StorageSettings.setIndexStorageOptimized(boolean)
