sqlitedict
has not been updated since late 2022 and has a high risk security vulnerability (CVE-2024-35515). WhileCharLMEmbeddings
is deprecated, removing the vulnerable dependency is still important for overall project health and security scanning. I've chosendiskcache
as the migration as it provides persistent key-value storage with features like automatic eviction, size limits, and thread/process safety, often exceeding sqlitedict's capabilities. It uses SQLite as one of its backends by default, offering a similar persistence mechanism. It also has no security vulnerabilities listed in the OSV database.
