Why in the API rework was StoreName not specified in the table method of Kafka StreamsBuilder?

Question

In the Kafka StreamsBuilder the signature for table is only:

table(java.lang.String topic)

https://kafka.apache.org/10/javadoc/org/apache/kafka/streams/StreamsBuilder.html

Where as before you were able to provide a store name:

table(java.lang.String topic, java.lang.String queryableStoreName)

https://kafka.apache.org/0110/javadoc/org/apache/kafka/streams/kstream/KStreamBuilder.html

Why was this removed?

Answer 1

It was not removed, but the API was reworked. Please read the upgrade notes for API changes: https://kafka.apache.org/11/documentation/streams/upgrade-guide

For this change in particular, the full details are documented via KIP-182: https://cwiki.apache.org/confluence/display/KAFKA/KIP-182%3A+Reduce+Streams+DSL+overloads+and+allow+easier+use+of+custom+storage+engines

You can specify the store name via Materialized parameter now:

table(String topic, Materialized materialized);
