Which Delta project/connector is this regarding?
Description
As integrated with the DynamoDBLogStore to ensure multiple writes, there are some problems working with the eventual consistent filesystem, while the listFrom API is not guaranteed to see the latest committed files.
In this patch, put the pre-commit files in the DynamoDB as a cache.
How was this patch tested?
It was tested in a (pyspark) multi-writing occasion with the SwiftStack(which uses the eventual consistency). While with the original version, multiple spark session returned the 'FileNotFoundException'. With this patch it ran correctly.
Does this PR introduce any user-facing changes?
No
