Examples of BlobCache

org.apache.flink.runtime.blob.BlobCache
The BLOB cache implements a local cache for content-addressable BLOBs. When requesting BLOBs through the {@link BlobCache#getURL} methods, the BLOB cache will first attempt serve the file from its local cache. Only if thelocal cache does not contain the desired BLOB, the BLOB cache will try to download it from the BLOB server.
This class is thread-safe.
