Hi,
I have a question regarding BlobStore listing.
We are currently using the FileSystem storage implementation
private long containerSize(String containerName) {
long containerSize = 0;
String marker = null;
PageSet<? extends StorageMetadata> containerSML = null;
ListContainerOptions lcoRecursive = new ListContainerOptions().recursive();
(1) containerSML = blobStore.list(containerName, lcoRecursive);
containerSize += pageSize(containerSML);
marker = containerSML.getNextMarker();
while (marker != null) {
lcoRecursive.afterMarker(marker);
(2) containerSML = blobStore.list(containerName, lcoRecursive);
containerSize += pageSize(containerSML);
marker = containerSML.getNextMarker();
}
log.debug("container:{} size:{}", containerName, containerSize);
return containerSize;
}
private long pageSize(PageSet<? extends StorageMetadata>
containerStorageMetadataList) {
long size = 0;
for (StorageMetadata containerStorageMetadata : containerStorageMetadataList) {
if (containerStorageMetadata.getType() == StorageType.BLOB) {
log.debug("name:{} size:{}", containerStorageMetadata.getName(),
containerStorageMetadata.getSize());
size += containerStorageMetadata.getSize();
} else {
log.debug("other in container: {}", containerStorageMetadata.getType());
}
}
return size;
}
By calling list() with ListContainerOptions().recursive() on both (1) and (2),
all container’s blobs are opened every PageSet.
I tried to call list() with recursive() on (1) only then iterating over
PageSets without the recursive flag set but I don’t get all Blobs.
Is there a way to iterate over all blobs in a container in a more effective way
?
Thanks,
Ionel
