_Painless_ is a simple, secure scripting language designed specifically for use
|
|
|
|
|
with Elasticsearch. It is the default scripting language for Elasticsearch and
|
|
|
|
|
can safely be used for inline and stored scripts. To get started with
|
|
|
|
|
Painless, see the {painless}/painless-guide.html[Painless Guide]. For a
|
|
|
|
|
detailed description of the Painless syntax and language features, see the
|
|
|
|
|

provides:
|
|
|
|
|
|
|
|
|
|
* Fast performance: Painless scripts https://benchmarks.elastic.co/index.html#search_qps_scripts[
|
|
|
|
|
run several times faster] than the alternatives.
|
|
|
|
|
|
|
|
|
|
* Safety: Fine-grained whitelist with method call/field granularity. See the
|
|

|
|
|
|
|
complete list of available classes and methods.

|
|
|
|
|
dynamic `def` type.
|
|
|
|
|
|
|
|
|
|
* Syntax: Extends a subset of Java's syntax to provide additional scripting
|
|
|
|
|
language features.
|
|
|
|
|
|
|
|
|
|
* Optimizations: Designed specifically for Elasticsearch scripting.
