What you'll learn

How to install and set up ingestr in seconds

Connect to AppsFlyer and AWS Athena with proper authentication

Copy entire tables or specific data with a single command

Set up incremental loading for continuous data synchronization

Prerequisites

Python 3.8 or higher installed
API token from AppsFlyer account
AWS credentials
S3 bucket access
AWS Glue Catalog permissions

Step 1: Install ingestr

Install ingestr in seconds using pip. Choose the method that works best for you:

Recommended: Using uv (fastest)

# Install uv first if you haven't already
pip install uv

# Run ingestr using uvx
uvx ingestr

Alternative: Global installation

# Install globally using uv
uv pip install --system ingestr

# Or using standard pip
pip install ingestr

Verify installation: Run ingestr --version to confirm it's installed correctly.

Step 2: Your First Migration

Let's copy a table from AppsFlyer to AWS Athena. This example shows a complete, working command you can adapt to your needs.

Set up your connections

AppsFlyer connection format:

appsflyer://?api_key=<api-key>

Parameters:

• api_key: API token for accessing AppsFlyer API

AWS Athena connection format:

athena://?bucket=<your-destination-bucket>&access_key_id=<your-aws-access-key-id>&secret_access_key=<your-aws-secret-access-key>&region_name=<your-aws-region>

Parameters:

• bucket: S3 bucket name for storing Parquet files
• access_key_id: AWS access key ID for authentication
• secret_access_key: AWS secret access key for authentication
• region_name: AWS region for Athena service and S3 buckets
• workgroup: Athena workgroup name
• profile: AWS profile name to use

BigQuery Setup Required

Before running the command:

Create a service account in Google Cloud Console
Grant it BigQuery Data Editor and Job User roles
Download the JSON key file
Use the path to this file in your connection string

Run your first copy

Copy the entire users table from AppsFlyer to AWS Athena:

ingestr ingest \
    --source-uri 'appsflyer://?api_key=ey123' \
    --source-table 'campaigns' \
    --dest-uri 'athena://?bucket=bucket_123&access_key_id=access_123&secret_access_key=secret_123&region_name=eu-central-1' \
    --dest-table 'raw.campaigns'

What this does:

• Connects to your AppsFlyer database
• Reads all data from the specified table
• Creates the table in AWS Athena if needed
• Copies all rows to the destination

Command breakdown:

--source-uri Your source database
--source-table Table to copy from
--dest-uri Your destination
--dest-table Where to write data

Step 3: Verify your data

After the migration completes, verify your data was copied correctly:

Check row count in AWS Athena:

-- Run this in AWS Athena
SELECT COUNT(*) as row_count 
FROM raw.campaigns;

-- Check a sample of the data
SELECT * 
FROM raw.campaigns 
LIMIT 10;

Advanced Patterns

Once you've mastered the basics, use these patterns for production workloads.

Only copy new or updated records since the last sync. Perfect for daily updates.

ingestr ingest \
    --source-uri 'appsflyer://?api_key=ey123' \
    --source-table 'public.orders' \
    --dest-uri 'athena://?bucket=bucket_123&access_key_id=access_123&secret_access_key=secret_123&region_name=eu-central-1' \
    --dest-table 'raw.orders' \
    --incremental-strategy merge \
    --incremental-key updated_at \
    --primary-key order_id

How it works: The merge strategy updates existing rows and inserts new ones based on the primary key. Only rows where updated_at has changed will be processed.

Common Use Cases

Ready-to-use commands for typical AppsFlyer to AWS Athena scenarios.

Daily Customer Data Sync

Keep your analytics warehouse updated with the latest customer information every night.

# Add this to your cron job or scheduler
ingestr ingest \
    --source-uri 'appsflyer://?api_key=ey123' \
    --source-table 'public.customers' \
    --dest-uri 'athena://?bucket=bucket_123&access_key_id=access_123&secret_access_key=secret_123&region_name=eu-central-1' \
    --dest-table 'analytics.customers' \
    --incremental-strategy merge \
    --incremental-key updated_at \
    --primary-key customer_id

Historical Data Migration

One-time migration of all historical records to your data warehouse.

# One-time full table copy
ingestr ingest \
    --source-uri 'appsflyer://?api_key=ey123' \
    --source-table 'public.transactions' \
    --dest-uri 'athena://?bucket=bucket_123&access_key_id=access_123&secret_access_key=secret_123&region_name=eu-central-1' \
    --dest-table 'warehouse.transactions_historical'

Development Environment Sync

Copy production data to your development AWS Athena instance (with sensitive data excluded).

# Copy sample data to development
ingestr ingest \
    --source-uri 'appsflyer://?api_key=ey123' \
    --source-table 'public.products' \
    --dest-uri 'athena://?bucket=bucket_123&access_key_id=access_123&secret_access_key=secret_123&region_name=eu-central-1' \
    --dest-table 'dev.products' \
    --limit 1000  # Only copy 1000 rows for testing

Troubleshooting Guide

Solutions to common issues when migrating from AppsFlyer to AWS Athena.

Connection refused or timeout errors

Check your connection details:

Authentication failures

Common authentication issues:

Schema or data type mismatches

Handling data type differences:

ingestr automatically handles most type conversions

Performance issues with large tables

Optimize large data transfers:

Use incremental loading to process data in chunks
Run migrations during off-peak hours
Split very large tables by date ranges using interval parameters
