/**
|
|
* Command to delete an entity (or entities) in Datastore specified by raw key ids, which can be
|
|
* found in Datastore Viewer in the AppEngine console -- it's the really long alphanumeric key that
|
|
* is labeled "Entity key" on the page for an individual entity.
|
|
*
|
|
* <p><b>WARNING:</b> This command can be dangerous if used incorrectly as it can bypass checks on
|
|
* deletion (including whether the entity is referenced by other entities) and it does not write
|
|
* commit log entries for non-registered types. It should mainly be used for deleting testing or
|
|
* malformed data that cannot be properly deleted using existing tools. Generally, if there already
|
|
* exists an entity-specific deletion command, then use that one instead.
