Cache statistics

Usage

gr_cache_stats(cache)

Arguments

cache

A gr_cache().

Value

A one-row data frame: dir, entries, bytes, hits, misses, writes and legacy_hits. entries and bytes are read from disk, so they include entries written by earlier sessions; the counters cover this session only. legacy_hits is how many of the hits were found under the old readgpt-cache-v2 key (see gr_cache()).

Examples

cache <- gr_cache(file.path(tempdir(), "harnessr-stats-cache"))
cl <- gr_cache_client(gr_mock_client(function(m, p) "hi"), cache)
invisible(gr_call(cl, "one"))
invisible(gr_call(cl, "one"))
gr_cache_stats(cache)[c("entries", "hits", "misses", "writes")]
