​
Overview

This guide walks through how to leverage the gluestick to_singer function to include typing information in payloads sent to your target, and how to send primary key(s) which can be useful when pushing to databases.

​
Setup your environment

​
Dependencies

The script we will walk through is tested with the following requirements.txt – if you have different behavior, verify your dependency versions match.

​
Verify your gluestick version

Ensure that the gluestick library version is 1.0.9 or greater or the to_singer function will not be available!
requirements.txt
pandas==1.3.5
gluestick==1.0.9
numpy==1.23.1

Sample Script

​
Typing with pandas

First you will need to ensure your pandas dataframe has the correct types when the data is exported to the target. This is generally achieved using the astype function Refer to the sample script below which:
  • Reads the products CSV as pandas dataframe,
  • Does some light transformation on the data, and
  • Casts the types of the columns in the dataframe
etl.py
# Import dependencies
import gluestick as gs
import pandas as pd
import os

# Establish standard directories for hotglue
ROOT_DIR = os.environ.get("ROOT_DIR", ".")
INPUT_DIR = f"{ROOT_DIR}/sync-output"
OUTPUT_DIR = f"{ROOT_DIR}/etl-output"

# Read input data
input_data = gs.read_csv_folder(INPUT_DIR)

# Get the products dataframe
products = input_data["products"]

# Explode the variants column
products = gs.explode_json_to_rows(products, "variants")

# Create an active flag column that is a boolean
products["active"] = products["status"]=="active"
# Convert the created_at column to datetime type
products["created_at"] = pd.to_datetime(products["created_at"])

# Rename some of the exploded columns
names = {
    "variants.id": "variants_id", 
    "variants.sku": "variants_sku", 
    "variants.price": "price", 
    "variants.title": "variants_title", 
    "variants.inventory_quantity": "inventory_quantity"
}
products = products.rename(names, axis=1)

# Select just the relevant columns
products = products[["id", "active", "vendor", "title", "variants_id", "variants_sku", "price", "variants_title", "inventory_quantity", "created_at"]]

# Force pandas to use the correct types
types = {
    "id": int,
    "active": bool,
    "vendor": "string", 
    "title": "string", 
    "variants_id": int, 
    "variants_sku": "string", 
    "price": float, 
    "variants_title": "string", 
    "inventory_quantity": int,
}

products = products.astype(types)

​
Export the data

Now that your dataframe has the types set, we can export the data using the gluestick to_singer function. The arguments of the to_singer function are:
ArgumentDescription
dfthe dataframe to write. In this case, products
namethe name of the table, will be used by the target. In this case, products
dirthe directory to write the data.singer file to. Should always be OUTPUT_DIR when using hotglue
keysan array of primary keys to use for this table
Refer to the sample script below:
etl.py

# Write the data as a data.singer file in the etl-output directory
gs.to_singer(products, "products", OUTPUT_DIR, keys=["id", "variants_id"])
This generates the following output (download here)
data.singer
