Red Panda

Easily interact with cloud (AWS) in your Data Science workflow.


  • DataFrame/files to and from S3 and Redshift.
  • Run queries on Redshift in Python.
  • Use built-in Redshift admin queries, such as checking running queries and errors.
  • Use Redshift utility functions to easily accomplish common tasks such as creating a table.
  • Manage files on S3.
  • Query data on S3 directly with Athena.
  • Pandas DataFrame utility functions.


pip install red-panda

Using red-panda

Import red-panda and create an instance of RedPanda. If you create the instance with dryrun=True (i.e. rp = RedPanda(redshift_conf, s3_conf, dryrun=True)), red-panda will print the planned queries instead of executing them.

from red_panda import RedPanda

redshift_conf = {
    "user": "awesome-developer",
    "password": "strong-password",
    "host": "",
    "port": 5432,
    "dbname": "awesome-db",

aws_conf = {
    "aws_access_key_id": "your-aws-access-key-id",
    "aws_secret_access_key": "your-aws-secret-access-key",
    # "aws_session_token": "temporary-token-if-you-have-one",

rp = RedPanda(redshift_conf, aws_conf)

Load your Pandas DataFrame into Redshift as a new table.

import pandas as pd

df = pd.DataFrame(data={"col1": [1, 2], "col2": [3, 4]})

s3_bucket = "s3-bucket-name"
s3_path = "parent-folder/child-folder" # optional, if you don't have any sub folders
s3_file_name = "test.csv" # optional, randomly generated if not provided
rp.df_to_redshift(df, "test_table", bucket=s3_bucket, path=s3_path, append=False)

It is also possible to:

  • Upload a DataFrame or flat file to S3.
  • Delete files from S3.
  • Load S3 data into Redshift.
  • Unload a Redshift query result to S3.
  • Obtain a Redshift query result as a DataFrame.
  • Run any query on Redshift.
  • Download S3 file to local.
  • Read S3 file in memory as DataFrame.
  • Run built-in Redshift admin queries, such as getting running query information.
  • Use utility functions such as create_table to quickly create tables in Redshift.
  • Run queries against S3 data directly with Athena using AthenaUtils.
  • Use features separately with RedshiftUtils, S3Utils, AthenaUtils.
s3_key = s3_path + "/" + s3_file_name

# DataFrame uploaded to S3
rp.df_to_s3(df, s3_bucket, s3_key)

# Delete a file on S3
rp.delete_from_s3(s3_bucket, s3_key)

# Upload a local file to S3
pd.to_csv(df, "test_data.csv", index=False)
rp.file_to_s3("test_data.csv", s3_bucket, s3_key)

# Populate a Redshift table from S3 files
# Use a dictionary for column definition, here we minimally define only data_type
redshift_column_definition = {
    "col1": {data_type: "int"},
    "col2": {data_type: "int"},
    s3_bucket, s3_key, "test_table", column_definition=redshift_column_definition

# Unload Redshift query result to S3
sql = "select * from test_table"
rp.redshift_to_s3(sql, s3_bucket, s3_path+"/unload", prefix="unloadtest_")

# Obtain Redshift query result as a DataFrame
df = rp.redshift_to_df("select * from test_table")

# Run queries on Redshift
rp.run_query("create table test_table_copy as select * from test_table")

# Download S3 file to local
rp.s3_to_file(s3_bucket, s3_key, "local_file_name.csv")

# Read S3 file in memory as DataFrame
df = rp.s3_to_df(s3_bucket, s3_key, delimiter=",") # csv file in this example

# Since we are only going to use Redshift functionalities, we can just use RedshiftUtils
from red_panda.red_panda import RedshiftUtils
ru = RedshiftUtils(redshift_conf)

# Run built-in Redshift admin queries, such as getting running query information
load_errors = ru.get_load_error(as_df=True)

# Use utility functions such as create_table to quickly create tables in Redshift
ru.create_table("test_table", redshift_column_definition, sortkey=["col2"], drop_first=True)

In no particular order:

  • Support more data formats for copy. Currently only support delimited files.
  • Support more data formats for s3 to df. Currently only support delimited files.
  • Improve tests and docs.
  • Better ways of inferring data types from dataframe to Redshift.
  • Explore using S3 Transfer Manager’s upload_fileobj for df_to_s3 to take advantage of automatic multipart upload.
  • Add COPY from S3 manifest file, in addition to COPY from S3 source path.
  • Support multi-cloud.
  • Take advantage of Redshift slices for parallel processing. Split files for COPY.
