## What is the reason for your feedback?

[ ] Missing the information I need

[ ] Too complicated

[x] Out of date

[ ] Something is broken

[ ] Other

## Additional details
What's the default behavior for `--store` without specifying `size`? The doc says it's 100% and it may be out-of-date. A customer try to restoring a prod db to a docker cluster it says:
```pausing due to error; use RESUME JOB to try to proceed once the issue is resolved, or CANCEL JOB to rollback: store 8 has insufficient remaining capacity to ingest data (remaining: 2.9 GiB / 4.9%, min required: 5.0%) ```
Could we verify and update the doc? Thanks!
