Method Detail

windowed

Stores.PersistentKeyValueFactory<K,V> windowed(long windowSize,
                                               long retentionPeriod,
                                               int numSegments,
                                               boolean retainDuplicates)

Deprecated.

Set the persistent store as a windowed key-value store

Parameters:

windowSize - size of the windows

retentionPeriod - the maximum period of time in milli-second to keep each window in this store

numSegments - the maximum number of segments for rolling the windowed store

retainDuplicates - whether or not to retain duplicate data within the window

sessionWindowed

Stores.PersistentKeyValueFactory<K,V> sessionWindowed(long retentionPeriod)

Deprecated.

Set the persistent store as a SessionStore for use with SessionWindows

Parameters:

retentionPeriod - period of time in milliseconds to keep each window in this store

enableLogging

Stores.PersistentKeyValueFactory<K,V> enableLogging(java.util.Map<java.lang.String,java.lang.String> config)

Deprecated.

Indicates that a changelog should be created for the store. The changelog will be created with the provided cleanupPolicy and configs. Note: Any unrecognized configs will be ignored.

Parameters:

config - any configs that should be applied to the changelog

Returns:

the factory to create a persistent key-value store

disableLogging

Stores.PersistentKeyValueFactory<K,V> disableLogging()

Deprecated.

Indicates that a changelog should not be created for the key-value store

Returns:

the factory to create a persistent key-value store

enableCaching

Stores.PersistentKeyValueFactory<K,V> enableCaching()

Deprecated.

Caching should be enabled on the created store.

Returns:

the factory to create a persistent key-value store

build

StateStoreSupplier build()

Deprecated.

Return the instance of StateStoreSupplier of new key-value store.

Returns:

the key-value store; never null
