PPL – Piped Processing Language

Piped Processing Language (PPL) is a query language that lets you use pipe (|) syntax to explore, discover, and query data stored in OpenSearch.

To quickly get up and running with PPL, use Query Workbench in OpenSearch Dashboards. To learn more, see Workbench.

The PPL syntax consists of commands delimited by the pipe character (|) where data flows from left to right through each pipeline.

search command | command 1 | command 2 ...

You can only use read-only commands like search, where, fields, rename, dedup, stats, sort, eval, head, top, and rare.

Quick start

To get started with PPL, choose Dev Tools in OpenSearch Dashboards and use the bulk operation to index some sample data:

PUT accounts/_bulk?refresh
{"account_number":1,"balance":39225,"firstname":"Amber","lastname":"Duke","age":32,"gender":"M","address":"880 Holmes Lane","employer":"Pyrami","email":"","city":"Brogan","state":"IL"}
{"account_number":6,"balance":5686,"firstname":"Hattie","lastname":"Bond","age":36,"gender":"M","address":"671 Bristol Street","employer":"Netagy","email":"","city":"Dante","state":"TN"}
{"account_number":13,"balance":32838,"firstname":"Nanette","lastname":"Bates","age":28,"gender":"F","address":"789 Madison Street","employer":"Quility","city":"Nogal","state":"VA"}
{"account_number":18,"balance":4180,"firstname":"Dale","lastname":"Adams","age":33,"gender":"M","address":"467 Hutchinson Court","email":"","city":"Orick","state":"MD"}

Go to Query Workbench and select PPL.

The following example returns firstname and lastname fields for documents in an accounts index with age greater than 18:

search source=accounts
| where age > 18
| fields firstname, lastname
