.config ⇒ Object

Note:

cache configurations must be set before initial use, when the caches are allocated.

Configuration, used open for configuring constants used within the codebase.

Defaults:

  • node_cache_size: cache_size

Examples:

set default cache size to be at most 10,000 entries


RDF.config.cache_size = 10_000

set cache size for interned URIs to 5,000 entries


RDF.config.uri_cache_size = 5_000
