Object storage (also known as object-based storage [1] or blob storage) is a computer data storage approach that manages data as "blobs" or "objects", as opposed to other storage architectures like file systems, which manage data as a file hierarchy, and block storage, which manages data as blocks within sectors and tracks. [2]
Amazon EBS (elastic block store) is an example of a cloud block store. [2] Cloud block-level storage will usually offer facilities such as replication for reliability, or backup services. [3] Block-level storage is in contrast to an object store or 'bucket store', such as Amazon S3 (simple storage service), or to a database. These operate at a ...
As of Java 8, Java supports functions as first class objects. Lambda expressions of this form are considered of type Function<T,U> with T being the domain and U the image type. The expression can be called with its .apply(T t) method, but not with a standard method call.
If the storage system identifies a block which it has already stored, only a reference to the existing block is stored, rather than the whole new block. The advantage of in-line deduplication over post-process deduplication is that it requires less storage and network traffic, since duplicate data is never stored or transferred.
DBMSes often use their own block I/O for improved performance and recoverability as compared to layering the DBMS on top of a file system. On Linux the default block size for most file systems is 4096 bytes. The stat command part of GNU Core Utilities can be used to check the block size. In Rust a block can be read with the read_exact method. [6]
Distributed block storage is a computer data storage architecture that the data is stored in volumes (known as blocks, a term dating back to Project Stretch [1]) across multiple physical servers, as opposed to other storage architectures like file systems which manages data as a file hierarchy, and object storage which manages data as objects ...
In computer programming, thread-local storage (TLS) is a memory management method that uses static or global memory local to a thread. The concept allows storage of data that appears to be global in a system with separate threads. Many systems impose restrictions on the size of the thread-local memory block, in fact often rather tight limits.
MinIO is an object storage system released under GNU Affero General Public License v3.0. [3] It is API compatible with the Amazon S3 cloud storage service. It is capable of working with unstructured data such as photos, videos, log files, backups, and container images with the maximum supported object size being 50TB.
