Qlik Replicate - S3 calculate consumission

[MigueldelCampo]

Good day, everyone.

I need some guidance on how to calculate the storage space I should reserve in my S3 plan.

Also, what best practices do you recommend for purging data to avoid saturating the plan?

We're migrating to Capacity configuration, and I'm having trouble figuring out which S3 plan would be the most suitable.

Data persistence is very low.

Thanks in advance

Hello,

Qlik Replicate does not provide a built-in way to calculate Amazon S3 storage consumption. Usage depends on full load size, CDC change volume, file format, and retention period.

Estimation:
Full Load size + (Daily CDC volume × retention days) + ~10% overhead

Best Practices:

1.Use Parquet format to reduce storage

2.Apply S3 lifecycle policies to delete/archive old CDC files

3.Tune CDC batching to avoid too many small files

4.Monitor usage using AWS S3 metrics / Cost Explorer
