Index has Changed Operation

IndexHasChangedOperation will let you check if the given index definition differs from the one on a server. This might be useful when you want to check the prior index deployment, if the index will be overwritten, and if indexing data will be lost.


public IndexHasChangedOperation(IndexDefinition definition)
indexDef IndexDefinition index definition
Return Value
true if an index does not exist on a server
true if an index definition does not match the one from the indexDef parameter
false if there are no differences between an index definition on the server and the one from the indexDef parameter


Boolean ordersIndexHasChanged =
    store.maintenance().send(new IndexHasChangedOperation(ordersIndexDefinition));
