> Project: Apache AsterixDB
> Issue Type: Improvement
> Components: STO - Storage

> Priority: Major
> Labels: triaged
> Fix For: 0.9.10
>
>
> There may be cases where the number of columns is too large to fit within the
> standard pageSize. This can prevent a tuple from being added to the dataset
> and may also trigger a flush failure, leading to repeated I/O retries that
> ultimately fail.
> To mitigate this issue, we can expand pageZero to accommodate the necessary
> metadata.
