memoise::cache_filesystem()cache_fs2.Rdmemoise::cache_filesystem() stores all caches in a single directory
which degrades filesystem performance when you have a large number
of cache files. This function adds a second level subdirectory structure
to help mitigate this issue. Future versions will enable the caller
to choose the number of levels. This works with all digest::digest()
hashing algorithms.
cache_fs2(path, algo = "xxhash64", compress = FALSE)
| path | Directory in which to store cached items. |
|---|---|
| algo | The hashing algorithm used for the cache, see |
Two additional functions are provided in slots in the returned list:
location() which will return the path to the cache directory
size() which will compute and return the size of the cache (in bytes)
