For batch ELT from CRM and ERP systems, you typically want a cloud data warehouse optimized for structured data, SQL analytics, scalability, and low ops overhead.
Good warehouse options
1. Snowflake
Best if you want:
- Very fast setup
- Strong support for batch ELT
- Separation of storage and compute
- Easy scaling for mixed workloads
- Good integration with common ETL/ELT tools
2. Google BigQuery
Best if you want:
- Fully managed serverless warehouse
- Minimal infrastructure management
- Strong SQL analytics
- Good fit for large batch loads and ad hoc analysis
3. Amazon Redshift
Best if you want:
- AWS-native warehouse
- Good if your stack is already on AWS
- Strong performance for relational analytics
- More tuning/ops than Snowflake or BigQuery, but mature
4. Azure Synapse Analytics
Best if you want:
- Azure-native ecosystem
- Integration with Microsoft tooling
- Suitable for enterprises already standardized on Azure
Recommendation
If you’re starting from scratch and want the simplest path for batch ELT from CRM/ERP:
- Snowflake is usually the safest general-purpose choice
- BigQuery is excellent if you prefer serverless and are on GCP
- Redshift if you’re committed to AWS
Key warehouse capabilities to look for
For CRM/ERP batch ELT, make sure the warehouse supports:
- Bulk loading from files / object storage
- Incremental loads and upserts / MERGE
- Strong SQL transformations
- Concurrency for BI and data engineering
- Role-based access control
- Auditability and data retention
- Schema evolution handling
Typical architecture
- CRM/ERP source systems
- Batch extraction into landing zone (S3 / GCS / ADLS)
- ELT into warehouse raw/staging layer
- Transform into curated marts
- BI/analytics on top
If you want, I can also recommend the best warehouse based on your cloud provider, data volume, and budget.
