Storage Requirement Calculator

Estimate storage requirements based on ingestion rate, retention, replication, compression, and overhead.

Data Ingestion

Records Per Day

Average Record Size

Retention & Multipliers

Retention Period (days)

Replication Factor

e.g., 3 replicas for fault tolerance

Compression Ratio

2 = data compresses to 1/2 size

Index/Metadata Overhead (%)

Headroom (%)

Extra capacity for spikes (recommend 20-30%)

Sizing Tips

Consider:
- Replication for distributed systems (Kafka, ES)
- Index overhead varies (10-30%)
- Compression depends on data type
- Always add headroom for growth

Common Compression Ratios:
- JSON/Text: 3-5x
- Columnar (Parquet): 5-10x
- Binary data: 1.5-2x
