Hi,
My Ignite version is 1.9.0
I am pushing JSON object into Ignite's cache using Apache Nifi's : GetKafka
=> PutIgniteCache processors.
I could able to save the data in cache but the data it is in byte array
format how can I query this.
My Json object looks like this : {"id":1, "name":"USA", "population":
150000} .
When print the cache data got the following result:
byte[] bytes = (byte[]) cache.get("1");
String str = new String(bytes, StandardCharsets.UTF_8);
System.out.println("Cache get id = "+str);
Iterator it=cache.iterator();
while(it.hasNext()){
System.out.println("Cache next=="+it.next());
}
Result:
Cache get id = {"id":1, "name":"USA", "population": 150000}
Cache next==Entry [key=1, val=[B@5ab14cb9]
Cache next==Entry [key=2, val=[B@5fb97279]
Cache next==Entry [key=3, val=[B@439a8f59]
How can I query this data or map this as key, value.
