ES|QL and Pandas
editES|QL and Pandas
editThe Elasticsearch Query Language (ES|QL) provides a powerful way to filter, transform, and analyze data stored in Elasticsearch. Designed to be easy to learn and use, it is a perfect fit for data scientists familiar with Pandas and other dataframe-based libraries. ES|QL queries produce tables with named columns, which is the definition of dataframes.
This page shows you an example of using ES|QL and Pandas together to work with dataframes.

Convert the dataset
editUse the ES|QL CSV import to convert the employees dataset to a Pandas
dataframe object.
from io import StringIO
from elasticsearch import Elasticsearch
import pandas as pd
client = Elasticsearch(
"https://[host].elastic-cloud.com",
api_key="...",
)
response = client.esql.query(
query="FROM employees | LIMIT 500",
format="csv",
)
df = pd.read_csv(StringIO(response.body))
print(df)
Even though the dataset contains only 100 records, a LIMIT of 500 is specified to suppress ES|QL warnings about potentially missing records. This prints the following dataframe:
avg_worked_seconds ... salary_change.long still_hired 0 268728049 ... 1 True 1 328922887 ... [-7, 11] True 2 200296405 ... [12, 14] False 3 311267831 ... [0, 1, 3, 13] True 4 244294991 ... [-2, 13] True .. ... ... ... ... 95 204381503 ... NaN False 96 206258084 ... -1 False 97 272392146 ... [-2, 4, 8] False 98 377713748 ... [-8, -3, 10, 14] True 99 223910853 ... [-7, 13] True
You can now analyze the data with Pandas or you can also continue transforming the data using ES|QL.
Analyze the data with Pandas
editIn the next example, the STATS … BY
command is utilized to count how many employees are speaking a given language.
The results are sorted with the languages column using
SORT:
response = client.esql.query(
query="""
FROM employees
| STATS count = COUNT(emp_no) BY languages
| SORT languages
| LIMIT 500
""",
format="csv",
)
df = pd.read_csv(
StringIO(response.body),
dtype={"count": "Int64", "languages": "Int64"},
)
print(df)
Note that the dtype parameter of pd.read_csv() is useful when the type
inferred by Pandas is not enough. The code prints the following response:
count languages 0 15 1 1 19 2 2 17 3 3 18 4 4 21 5
Pass parameters to a query with ES|QL
editUse the built-in parameters support of the ES|QL REST API to pass parameters to a query:
response = client.esql.query(
query="""
FROM employees
| STATS count = COUNT(emp_no) BY languages
| WHERE languages >= (?)
| SORT languages
| LIMIT 500
""",
format="csv",
params=[3],
)
df = pd.read_csv(
StringIO(response.body),
dtype={"count": "Int64", "languages": "Int64"},
)
print(df)
The code above outputs the following:
count languages 0 17 3 1 18 4 2 21 5
