These are not compile-time parameters. According to SQLite's
documentation, they are set at runtime using the sqlite3_config() API,
which is a C-style variadic function, so you can just pass however many
arguments are needed for that configuration item. I.e.:
sqlite3_config(SQLITE_CONFIG_MMAP_SIZE, 10_000_000_000, 30_000_000_000);
Since sqlite3_config is not thread-safe (according to the docs), you
must initialize it before any threads are started:
shared static this() {
sqlite3_config(SQLITE_CONFIG_MMAP_SIZE, 10_000_000_000,
30_000_000_000);
}
