Installation

[!NOTE] DremioFrame has many optional dependencies for advanced features like AI, Chart Exporting, and Distributed Orchestration. See Optional Dependencies for a full list.

pip install dremioframe

To install with optional dependencies (e.g., for static image export):

pip install "dremioframe[image_export]"

Quick Start

Dremio Cloud

from dremioframe.client import DremioClient

# Assumes DREMIO_PAT and DREMIO_PROJECT_ID are set in env
client = DremioClient()

# Query a table
df = client.table('finance.bronze.transactions').select("transaction_id", "amount", "customer_id").limit(5).collect()
print(df)

Dremio Software v26+

# Assumes DREMIO_SOFTWARE_HOST and DREMIO_SOFTWARE_PAT are set in env
client = DremioClient(mode="v26")

# Or with explicit parameters
client = DremioClient(
    hostname="v26.dremio.org",
    pat="your_pat_here",
    tls=True,
    mode="v26"
)

Dremio Software v25

client = DremioClient(
    hostname="localhost",
    username="admin",
    password="password123",
    tls=False,
    mode="v25"
)

Features

from dremioframe.client import DremioClient

# Assumes DREMIO_PAT and DREMIO_PROJECT_ID are set in env
client = DremioClient()

# List catalog
print(client.catalog.list_catalog())

# Query data
df = client.table('finance.bronze.transactions').select("transaction_id", "amount", "customer_id").filter("amount > 1000").collect()
print(df)

# Calculated Columns
df.mutate(amount_with_tax="amount * 1.08").show()

# Aggregation
df.group_by("customer_id").agg(total_spent="SUM(amount)").show()

# Joins
customers = client.table('finance.silver.customers')
df.join(customers, on="transactions.customer_id = customers.customer_id").show()

# Iceberg Time Travel
df.at_snapshot("123456789").show()

# API Ingestion
client.ingest_api(
    url="https://api.example.com/users",
    table_name="finance.bronze.users",
    mode="merge",
    pk="id"
)

# Charting
sales_summary = client.table('finance.gold.sales_summary')
sales_summary.chart(kind="bar", x="category", y="total_sales", save_to="sales.png")

# Export
df.to_csv("transactions.csv")
df.to_parquet("transactions.parquet")

# Insert Data (Batched)
import pandas as pd
data = pd.DataFrame({"id": [1, 2], "name": ["A", "B"]})
client.table("finance.bronze.raw_data").insert("finance.bronze.raw_data", data=data, batch_size=1000)

# SQL Functions
from dremioframe import F

client.table("finance.silver.sales") \
    .select(
        F.col("dept"),
        F.sum("amount").alias("total_sales"),
        F.rank().over(F.Window.order_by("amount")).alias("rank")

# Required for connecting to Dremio Software (v26+ recommended)
# DREMIO_SOFTWARE_PAT: Personal Access Token for Dremio Software
# DREMIO_SOFTWARE_HOST: Hostname/URL of your Dremio Software instance (e.g. dremio.example.com)
