Given that a language handler would be expected to be persistent, and to support concurrent (and reentrant) calls within a single database, is there a unique context or session identifier available?

Is there a place to store data, to be retrieved later in the same session?

Is there a place to store data (a cache?) that has been retrieved from the database for use by concurrent sessions using that database?


​PL/R also has an implementation for this kind of thing.
