海外TECH	DEV Community	SeaweedFS vs JuiceFS	https://dev.to/tonybarber2/seaweedfs-vs-juicefs-3dgp	SeaweedFS vs JuiceFSSeaweedFS is an efficient distributed file system that can read and write small data blocks quickly and is prototyped after Facebook s Haystack In this article we will compare the differences in design and features between SeaweedFS and JuiceFS to help readers make a better choice for themselves SeaweedFS System ArchitectureSeaweedFS consists of parts a Volume Server to store files in the underlying layer a Master Server to manage clusters and an optional Filer component to provide more features upwards Volume Server and Master ServerIn terms of system operation Volume Server and Master Server work together as file storage Volume Server focuses on writing and reading data and Master Server provides management service for clusters and Volumes When reading and writing data the implementation of SeaweedFS is similar to Haystack in that a user created Volume is a large disk file Superblock in the figure below In this Volume all files written by the user Needle in the figure below are merged into the large disk file Before starting to write data the caller needs to make a write request to SeaweedFS Master Server which then returns a File ID consisting of a Volume ID and offset based on the current amount of data along with basic metadata information such as file length and Chunk When the write is complete the caller needs to associate the file with the returned File ID in an external system e g MySQL When reading the data the contents of the file can be obtained very efficiently because the data can be directly referenced by File ID FilerOn top of the above mentioned underlying storage unit SeaweedFS provides a component called Filer which connects to the Volume Server and Master Server Thus it can provide rich functions and features such as POSIX support WebDAV S interface etc Like JuiceFS Filer also needs to use an external database to store metadata For the sake of illustration all the SeaweedFS mentioned below include Filer components JuiceFS ArchitectureJuiceFS uses a separate storage architecture for data and metadata where the file data itself is splitted and stored in an object store e g Amazon S while the metadata is stored in a database of the user s choice e g Redis MySQL By sharing the same Metadata Engine and object storage JuiceFS achieves a distributed file system with strong consistency guarantee and also has many features such as POSIX full compatibility and high performance Comparison in MetadataBoth SeaweedFS and JuiceFS support external databases to store metadata In terms of the supported databases SeaweedFS supports up to databases Due to high requirements for database transactions see below JuiceFS supports types of transactional databases in total Atomic OperationsTo ensure the atomicity of all metadata operations JuiceFS needs to use a transactional database at the implementation level SeaweedFS on the other hand has weaker requirements for database transaction capabilities And it only enables transactions for some of the databases SQL ArangoDB and TiKV when performing rename operations Also since the original directory or file is not locked when copying metadata during the rename operation data corruption may occur Change Log changelog SeaweedFS generates a changelog for all metadata operations which can be used for data replication see below operation auditing etc while JuiceFS does not implement this feature yet Comparison in StorageAs mentioned above the data storage of SeaweedFS is implemented by Volume Server Master Server which supports features such as merged storage and correction code for small data blocks The data storage of JuiceFS is based on Object Storage Service and the relevant features are provided by the user selected Object Storage File SplittingWhen storing data SeaweedFS and JuiceFS both split files into smaller chunks and then persist them in the underlying data system SeaweedFS splits files into MB chunks and for very large files over GB it also saves the chunk indexes to the underlying data system JuiceFS on the other hand splits into MB Chunks and then into MB Objects optimizing the performance of random writes sequential reads repeated writes etc by using the internal concept of a Slice See An introduction to the workflow of processing read and write for details Tiered StorageFor newly created Volumes SeaweedFS stores the data locally while for older Volumes SeaweedFS supports uploading them to the cloud to achieve tiered storage In this regard JuiceFS relies on external services Data CompressionJuiceFS supports data compression using LZ or ZStandard while SeaweedFS chooses compression algorithm based on the information such as extension and file type of the written files Storage EncryptionJuiceFS supports encryption in transit and encryption at rest When encryption at rest is enabled the user needs to provide a self managed key and all written data will be encrypted based on this key See Data Encryption for details SeaweedFS also supports in transit encryption and encryption at rest When data encryption is enabled all data written to Volume Server is encrypted with a random key and the information about the corresponding random key is managed by the Filer which maintains the metadata Access Protocols POSIX CompatibilityJuiceFS is fully POSIX compatible while SeaweedFS is only partially POSIX compatible see Issue and Wiki which is still being improved S ProtocolJuiceFS implements S gateway through MinIO S gateway It provides a S compatible RESTful API for files in JuiceFS and enables the management with tools such as scmd AWS CLI MinIO Client mc etc if mounting is not convenient SeaweedFS currently supports about S APIs covering common read write check and delete requests with extension of functions for some specific requests e g Read as detailed in Amazon S API WebDAV ProtocolBoth JuiceFS and SeaweedFS support the WebDAV protocol HDFS CompatibilityJuiceFS is fully compatible with the HDFS API not only with Hadoop x and Hadoop x but also with various components of the Hadoop ecosystem SeaweedFS provides basic compatibility with the HDFS API but some operations such as truncate concat checksum and extended attributes are not yet supported CSI DriversBoth JuiceFS and SeaweedFS provide a Kubernetes CSI Driver to help users use the corresponding file system in the Kubernetes ecosystem Extended Features Client side cachingJuiceFS has a variety of client side caching strategies covering everything from metadata to data caching and allows users to customize according to their scenarios details while SeaweedFS does not have client side caching capabilities Cluster Data ReplicationFor data replication between multiple clusters SeaweedFS supports two asynchronous replication modes Active Active and Active Passive both of which achieve consistency between different clusters through log replaying For each changelog there is a signature message to ensure that the same modification is not applied multiple times In Active Active mode where the number of cluster nodes exceeds some operations of SeaweedFS will be limited such as renaming directories JuiceFS does not natively support data synchronization between clusters and relies on the data replication capabilities of the metadata engine and the object store On cloud Data CachingSeaweedFS can be used as a cache for the object stored on the cloud and supports manual cache warm up Modifications to cached data are synchronized asynchronously to the object store JuiceFS needs to store files to the object store by chunks and does not yet support cache acceleration for data already in the object store TrashBy default JuiceFS enables the Trash feature which automatically moves user deleted files to the trash directory under the JuiceFS root directory for a specified period of time before the data is actually cleaned up SeaweedFS does not support this feature currently Operations and Maintenance ToolsJuiceFS provides two subcommands juciefs stats and juicefs profile allowing users to view real time or playback performance metrics from a certain time period JuiceFS has also developed an external metrics API that allows users to easily monitor using Prometheus and Grafana SeaweedFS supports both Push and Pull approaches to work with Prometheus and Grafana and provides an interactive weed shell tool for users to perform a range of operations and maintenance tasks e g checking the current cluster status listing files etc Other comparisonsIn terms of release date SeaweedFS was released in April and has accumulated K stars so far while JuiceFS was released in January and has accumulated K stars In terms of the project both JuiceFS and SeaweedFS adopt the commercial friendly Apache License SeaweedFS is mainly maintained by Chris Lu personally while JuiceFS is mainly maintained by Juicedata inc Both JuiceFS and SeaweedFS are written in Go language Comparison TableSeaweedFSJuiceFSMetadataMulti engineMulti engineAtomicity of Metadata OperationsNot
