Rakesh Radhakrishnan updated HDDS-5929:
---------------------------------------
Description:
Presently FILE_SYSTEM_OPTIMIZED("FSO") and OBJECT_STORE("OBS") implementation
depends on {{"ozone.om.enable.filesystem.paths"}} flag. This flag should be
enabled explicitly for the FSO logic and disabled explicitly for the OBS logic.
This task is to remove the dependency with the normalization config flag for
the FSO and OBS bucket layouts.
*case-1)* {{FSO bucket layout}} should normalize the given key path
irrespective of the above flag value.
*case-2)* {{OBS bucket layout}} shouldn't normalize the given key path
irrespective of the above flag value.
*case-3)* {{LEGACY bucket layout}} should read the configuration flag and
perform normalize the given key path based on the above config flag.
+*Hint*+
{code:java}
// normalize key if required.
String keyName;
if (getBucketLayout() == BucketLayout.OBJECT_STORE) {
keyName = keyArgs.getKeyName(); // pure object store semantics.
} else if (getBucketLayout() == BucketLayout.FILE_SYSTEM_OPTIMIZED) {
keyName = validateAndNormalizeKey(true, keyArgs.getKeyName()); // pure FS
semantics.
} else {
// legacy bucket, normalize key based on
"ozone.om.enable.filesystem.paths" flag value.
keyName = validateAndNormalizeKey(
ozoneManager.getEnableFileSystemPaths(), keyArgs.getKeyName());
}
{code}
