Sreeja updated HDDS-14937:
--------------------------
Description:
Iceberg provides [RewriteTablePath
|https://github.com/apache/iceberg/blob/1.10.x/api/src/main/java/org/apache/iceberg/actions/RewriteTablePath.java]
action that rewrites the table's metadata files(metadata json files , manifest
lists , manifest files and if any positional delete files) to a staging
directory, replacing all source prefixes in absolute paths with a specified
target prefix.
Ozone should implement this action to be able to natively change the source
prefixes in absolute paths with a specified target prefix in the metadata files
of the iceberg table with. zero data file copy.
Iceberg also provides the core util methods in
[RewriteTablePathUtil|https://github.com/apache/iceberg/blob/1.10.x/core/src/main/java/org/apache/iceberg/RewriteTablePathUtil.java]
that can be used to by Ozone for the same purpose.
