### Lookup options
-Flink lookup joins cache the whole projected dimension table in memory, and
the cache is kept in memory for the lifetime of the job, so the dimension table
should be populated before the join starts. See [Lookup
Join](flink-queries.md#lookup-join) for details. These options are set as table
options in the DDL, or per query with the `OPTIONS` hint.
+Flink lookup joins cache the whole projected dimension table in memory, and

| Lookup option | Default | Description
|
| ------------------------------ | ------- |
--------------------------------------------------------------------------------------------------
|
| `lookup.full-cache.eager-load` | `true` | Whether to load the full cache
when the lookup function is opened, instead of on the first lookup. |
+| lookup.full-cache.reload-strategy | (unset) | Selects the
reload strategy: `PERIODIC` reloads with a fixed interval, `TIMED` reloads at a
fixed time of day. No reload is configured when it is not set, and the options
below only configure the selected strategy. |
