S3 metadata table feature in other regions (not US East (N. Virginia), US East (Ohio), and US West (Oregon) Regions)

Currently, Amazon S3 Metadata is only available in three AWS regions: US East (N. Virginia), US East (Ohio), and US West (Oregon). Based on the available information, there is no specific timeline provided for when this feature will be expanded to additional regions.

While AWS has indicated that the feature would be "coming soon to additional Regions" when it was in preview, now that S3 Metadata is generally available, it remains limited to these three regions. If your team urgently needs this feature, you would need to use one of these three supported regions for now.

For the most up-to-date information on regional availability, I'd recommend checking the official Amazon S3 documentation or contacting AWS Support directly to inquire about expansion plans for this feature.
