### Core Functionality
- **Dry-run mode**: Add `--dry-run` flag to preview queries without execution
- **Query preview**: Show first 5 rows that would be affected by DELETE/UPDATE
- **Enhanced SQL parsing**: Support more complex queries (JOINs, subqueries, CTEs)
- **Transaction support**: Handle multi-statement transactions properly
- **Connection pooling**: Optimize database connections for better performance
### Enhanced Security
- **Multiple honeytokens**: Support configurable canary table names
- **IP-based restrictions**: Block/allow specific IP ranges
- **Rate limiting**: Prevent query spam from clients
- **User authentication**: Proxy-level user validation before DB access
- **Query signature detection**: Block known dangerous query patterns
### Configuration & Flexibility
- **Per-table row limits**: Configure different thresholds per table
```toml
[table_limits]
users = 100
products = 1000
logs = 10000
```
- **Regex-based table matching**: `sensitive_*` tables with stricter limits
### Monitoring & Observability
- **Structured JSON logging**: Machine-readable log format
- **Metrics endpoint**: Prometheus metrics on `/metrics`?
- **Query history**: Store and review blocked/allowed queries
### Backup Integration
- **Real snapshot support**: Integration with `pg_dump` or cloud backups
- **Backup verification**: Ensure backups are valid before destructive queries
- **Point-in-time recovery**: Automatic backup before major operations
- **Configurable backup storage**: S3, GCS, local filesystem support
### Query Analysis
- **Query cost estimation**: Use EXPLAIN to predict query performance
- **Execution plan analysis**: Block queries with expensive operations
- **Index usage detection**: Warn about queries not using indexes
- **Query optimization suggestions**: Recommend better query patterns
### Integration & APIs
- **REST API**: Control proxy settings via HTTP endpoints
- **Webhook notifications**: Send alerts to Slack/Discord on blocks
- **Database migration support**: Safe handling of schema changes
- **Multiple database support**: MySQL, SQLite proxy variants
### Testing & Development
- **Query simulation**: Test mode with fake data responses
- **Fuzzing support**: Automated testing with random queries
- **Benchmark suite**: Performance testing framework
- **Integration tests**: Full end-to-end testing setup
## Production Readiness
### Performance
- **Async query processing**: Non-blocking query analysis
- **Connection reuse**: Pool management for database connections
- **Query caching**: Cache COUNT query results for similar patterns
- **Batch query analysis**: Process multiple queries efficiently
### Security Hardening
- **TLS support**: Encrypted connections between client/proxy/database
- **Certificate validation**: Proper SSL/TLS certificate handling
### Deployment
- **Helm chart**: kinda OD but why not
- **Multi-architecture builds**: ARM64 and AMD64 Docker images
- **Health checks**: Proper liveness/readiness probes
