Sax > Assignee: highluck > Priority: Minor > Labels: beginner, newbie > > In Kafka 2.1.0 we deprecated couple of methods (KAFKA-7277) to pass in > timestamps via IQ API via Duration/Instance parameters instead of plain longs. > In Kafka 2.3.0 we introduced TimestampedXxxStores (KAFKA-3522) and allow IQ > to return the stored timestamp. > However, we never update our JavaDocs that contain code snippets to > illustrate how a local store can be queries. For example > `KGroupedStream#count(Materialized)` > ([https://github.com/apache/kafka/blob/trunk/streams/src/main/java/org/apache/kafka/streams/kstream/KGroupedStream.java#L116-L122]): > > {code:java} > * <pre>{@code * KafkaStreams streams = ... // counting words > * String queryableStoreName = "storeName"; // the store name should be the > name of the store as defined by the Materialized instance > * ReadOnlyKeyValueStore<String,Long> localStore = > streams.store(queryableStoreName, QueryableStoreTypes.<String, > Long>keyValueStore()); > * String key = "some-word"; > * Long countForWord = localStore.get(key); // key must be local (application > state is shared over all running Kafka Streams instances) > * }</pre> > {code} > We should update all JavaDocs to use `TimestampedXxxStore` and the new > Duration/Instance methods in all those code snippets. > -- This message was sent by Atlassian Jira (v8.3.4#803005)
