- def as[K, V](supplier: KeyValueBytesStoreSupplier)(implicit keySerde: Serde[K], valueSerde: Serde[V]): kstream.Materialized[K, V, ByteArrayKeyValueStore]
Materialize a org.apache.kafka.streams.state.KeyValueStore using the provided KeyValueBytesStoreSupplier.
Materialize a org.apache.kafka.streams.state.KeyValueStore using the provided KeyValueBytesStoreSupplier.
- K
key type of the store
- V
value type of the store
- supplier
the KeyValueBytesStoreSupplier used to materialize the store
- keySerde
the key serde to use.
- valueSerde
the value serde to use.
- returns
a new Materialized instance with the given supplier
- def as[K, V](supplier: SessionBytesStoreSupplier)(implicit keySerde: Serde[K], valueSerde: Serde[V]): kstream.Materialized[K, V, ByteArraySessionStore]
Materialize a org.apache.kafka.streams.state.SessionStore using the provided SessionBytesStoreSupplier.
Materialize a org.apache.kafka.streams.state.SessionStore using the provided SessionBytesStoreSupplier.
Important: Custom subclasses are allowed here, but they should respect the retention contract: Session stores are required to retain windows at least as long as (session inactivity gap + session grace period). Stores constructed via org.apache.kafka.streams.state.Stores already satisfy this contract.
- K
key type of the store
- V
value type of the store
- supplier
the SessionBytesStoreSupplier used to materialize the store
- keySerde
the key serde to use.
- valueSerde
the value serde to use.
- returns
a new Materialized instance with the given supplier
- def as[K, V](supplier: WindowBytesStoreSupplier)(implicit keySerde: Serde[K], valueSerde: Serde[V]): kstream.Materialized[K, V, ByteArrayWindowStore]
Materialize a org.apache.kafka.streams.state.WindowStore using the provided WindowBytesStoreSupplier.
Materialize a org.apache.kafka.streams.state.WindowStore using the provided WindowBytesStoreSupplier.
Important: Custom subclasses are allowed here, but they should respect the retention contract: Window stores are required to retain windows at least as long as (window size + window grace period). Stores constructed via org.apache.kafka.streams.state.Stores already satisfy this contract.
- K
key type of the store
- V
value type of the store
- supplier
the WindowBytesStoreSupplier used to materialize the store
- keySerde
the key serde to use.
- valueSerde
the value serde to use.
- returns
a new Materialized instance with the given supplier
- def as[K, V, S <: StateStore](storeName: String)(implicit keySerde: Serde[K], valueSerde: Serde[V]): kstream.Materialized[K, V, S]
Materialize a StateStore with the given name.
Materialize a StateStore with the given name.
- K
key type of the store
- V
value type of the store
- S
type of the StateStore
- storeName
the name of the underlying org.apache.kafka.streams.scala.kstream.KTable state store; valid characters are ASCII alphanumerics, '.', '_' and '-'.
- keySerde
the key serde to use.
- valueSerde
the value serde to use.
- returns
a new Materialized instance with the given storeName
