UnverifiedCopy-on-Write technology does not immediately copy all data when creating a replica; instead, it allows the new replica to share the same underlying storage pages as the source data, copying a storage page only when a write operation occurs.75% similarUnverifiedBtrfs uses a copy-on-write (CoW) mechanism that writes data to a new location rather than overwriting the original upon modification, which naturally produces more fragmentation than in-place update strategies.72% similarUnverifiedCLM transforms the context from an append-only linear sequence into a readable and writable working memory, where the model can retain, shrink, delete, or rewrite any part of it.66% similarUnverifiedPrompt caching takes effect in units of "prefix" and only works for content that is completely identical from the start; once a token in the middle changes, the content after it cannot hit the existing cache.65% similar
