Enum Class ScriptType

java.lang.Object
java.lang.Enum<ScriptType>
org.elasticsearch.script.ScriptType
All Implemented Interfaces:
Serializable, Comparable<ScriptType>, Constable, Writeable
public enum ScriptType extends Enum<ScriptType> implements Writeable
ScriptType represents the way a script is stored and retrieved from the ScriptService. It's also used to by ScriptService to determine whether or not a Script is allowed to be executed based on both default and user-defined settings.

  • Enum Constant Details

    • INLINE

      public static final ScriptType INLINE
      INLINE scripts are specified in numerous queries and compiled on-the-fly. They will be cached based on the lang and code of the script. They are turned off by default because most languages are insecure (Groovy and others), but can be overridden by the specific ScriptEngine if the language is naturally secure (Painless, Mustache, and Expressions).

    • STORED

      public static final ScriptType STORED
      STORED scripts are saved as part of the ClusterState based on user requests. They will be cached when they are first used in a query. They are turned off by default because most languages are insecure (Groovy and others), but can be overridden by the specific ScriptEngine if the language is naturally secure (Painless, Mustache, and Expressions).
