maximum_cache_size

size_t tatami_hdf5::CompressedSparseMatrixOptions::maximum_cache_size = 100000000

Size of the in-memory cache in bytes.

We cache all chunks required to read a row/column in tatami::MyopicDenseExtractor::fetch() and related methods. This allows us to re-use the cached chunks when adjacent rows/columns are requested, rather than re-reading them from disk.

Larger caches improve access speed at the cost of memory usage. Small values may be ignored as CompressedSparseMatrix will always allocate enough to cache a single element of the target dimension.
