bkt

bkt (pronounced "bucket") is a subprocess caching utility written in Rust.

$ bkt --help

CLI and Rust library for caching subprocess invocations

Usage: bkt [OPTIONS] --ttl <DURATION> -- <COMMAND>...

Arguments:

<COMMAND>... The command to run

Options:

--ttl <DURATION> Duration the cached result will be valid for [env: BKT_TTL=] [aliases:

time-to-live]

--stale <DURATION> Duration after which the result will be asynchronously refreshed

--warm Asynchronously execute and cache the given command, even if it's already cached

--force Execute and cache the given command, even if it's already cached

--cwd Includes the current working directory in the cache key, so that the same command

run in different directories caches separately [aliases: use-working-dir]

--env <NAME> Includes the given environment variable in the cache key, so that the same command

run with different values for the given variables caches separately [aliases:

use-environment]

--modtime <FILE> Includes the last modification time of the given file(s) in the cache key, so that

the same command run with different modtimes for the given files caches separately

[aliases: use-file-modtime]

--discard-failures Don't cache invocations that fail (non-zero exit code). USE CAUTION when passing

this flag, as unexpected failures can lead to a spike in invocations which can

exacerbate ongoing issues, effectively a DDoS

--scope <NAME> If set, all cached data will be scoped to this value, preventing collisions with

commands cached with different scopes [env: BKT_SCOPE=]

--cache-dir <DIR> The directory under which to persist cached invocations; defaults to the system's

temp directory. Setting this to a directory backed by RAM or an SSD, such as a

tmpfs partition, will significantly reduce caching overhead [env: BKT_CACHE_DIR=]
