Constants

const (
	EnforceIntraClusterAccess = Flags(1 << iota)
	SkipVC                    // (*) skip loading existing object's metadata, Version and Checksum (VC) in particular
	DontAutoDetectFshare      // do not auto-detect file share (NFS, SMB) when _promoting_ shared files to AIS
	S3APIviaRoot              // handle s3 requests via `aistore-hostname/` (default: `aistore-hostname/s3`)
	FsyncPUT                  // (*) when finalizing PUT(object): fflush prior to (close, rename) sequence
	LZ4Block1MB               // .tar.lz4 format, lz4 compression: max uncompressed block size=1MB (default: 256K)
	LZ4FrameChecksum          // checksum lz4 frames (default: don't)
	DontAllowPassingFQNtoETL  // do not allow passing fully-qualified name of a locally stored object to (local) ETL containers
	IgnoreLimitedCoexistence  // run in presence of "limited coexistence" type conflicts (same as e.g. CopyBckMsg.Force but globally)
	S3PresignedRequest        // (*) pass-through client-signed (presigned) S3 requests for subsequent authentication by S3
	DontOptimizeVirtualDir    // when prefix doesn't end with '/' and is a subdirectory: don't assume there are no _prefixed_ obj names
	DisableColdGET            // disable cold-GET (from remote bucket)
	StreamingColdGET          // write and transmit cold-GET content back to user in parallel, without _finalizing_ in-cluster object
	S3ReverseProxy            // intra-cluster communications: instead of regular HTTP redirects reverse-proxy S3 API calls to designated targets
	S3UsePathStyle            // use older path-style addressing (as opposed to virtual-hosted style), e.g., https://s3.amazonaws.com/BUCKET/KEY
