Enum Strategy 

pub enum Strategy {
    ReadWrite,
    ReadOnly,
}

How a region is kept in step with the database.

Variants

ReadWrite

Entities and queries are dropped when the table is written to.

The default, and the only one that is safe without knowing the application: a write bumps the table’s generation and every cached query for it becomes a miss.

ReadOnly

The table is never written to, so nothing is ever invalidated.

For reference data — countries, currencies, a list of statuses. It skips the generation read entirely, which is one round trip less per query, and it is a promise the caller makes: a write to a read-only region is served stale until the entry expires. Region::ttl is what bounds that, so a read-only region with no TTL is refused.
