Content-Addressable Storage
A data storage paradigm in which content is identified and addressed by a hash of its own contents, ensuring that identical content always maps to the same address. This approach guarantees integrity and deduplication and was popularized at scale by the Git version control system.
Core Facts
In the embedded token scenario, the server signs the token with a private key, and the Databricks platform uses the corresponding public key to verify the signature's integrity.
In Git, every file, directory, and commit has a SHA-1 hash computed as its address in the object database.
Timeline (last 90 days)
Content-addressed storage computes a hash fingerprint for files and stores only the changed parts.
Content-addressed storage identifies files by content hash values (such as SHA-1/SHA-256) rather than path names, automatically deduplicates identical content, and can precisely locate any historical version, and it is the underlying mechanism of modern version control systems such as Git.
Pure content addressing faces challenges in large-file scenarios, including time-consuming hash computation, complex garbage collection, and tension with the human-readable semantics of branch naming.

内容寻址存储（CAS）通过数据内容的哈希值而非存储位置来定位数据，IPFS是该理念最知名的实现
减少对单一平台的依赖、采用去中心化托管或内容寻址存储等多元化分发机制被认为能提升整体韧性
