provided
Key: HDDS-14938
URL: https://issues.apache.org/jira/browse/HDDS-14938
Project: Apache Ozone
Issue Type: Sub-task
Reporter: Sreeja
Assignee: Sreeja
This change introduces support for configuring Iceberg's *RewriteTablePath
action* that updates location prefixes across table metadata files within a
specified version range.
h3. *Key Features*
* *Prefix Rewrite Configuration*
** Allows specifying:
*** {{sourcePrefix}} (existing path prefix)
*** {{targetPrefix}} (replacement prefix)
** Ensures source and target prefixes are non-empty and not identical.
* *Version Range Support*
** Optional {{startVersion}} and {{endVersion}} inputs.
** Validates that provided version names exist in table metadata logs.
** Defaults:
*** {{endVersion}} → current metadata version if not provided
*** {{startVersion}} → optional (if not set, rewrite applies up to end version)
* *Staging Location Handling*
** Supports user-defined staging directory.
** If not provided, automatically generates a staging path using:
*** table metadata location
*** random UUID
** Ensures proper path formatting (trailing separator handling).
* *Metadata Validation*
** Ensures:
*** version exists in metadata log (current or previous files)
*** version file physically exists
** Matches versions using filename comparison.
