Hi all of you,

I am reading the following code :
..........
        KTable<String, Long> wordCounts = textLines
            .flatMapValues(textLine -> 
Arrays.asList(textLine.toLowerCase().split("\\W+")))
            .groupBy((key, word) -> word)
            .count(Materialized.<String, Long, KeyValueStore<Bytes, 
byte[]>>as("counts-store"));
.......... 

I do not understand this line 

count(Materialized.<String, Long, KeyValueStore<Bytes, 
byte[]>>as("counts-store"))

Please tell me where to read to understand this

Thank you,
Aurel
