KAFKA-5972 Flatten SMT does not work with null values
A bug in Flatten SMT while doing tests with different SMTs that are
provided out-of-box. Flatten SMT does not work as expected with schemaless JSON
that has properties with null values.
Example json:
{A={D=dValue, B=null, C=cValue}}
The issue is in if statement that checks for null value.
CURRENT VERSION:
for (Map.Entry<String, Object> entry : originalRecord.entrySet()) {
final String fieldName = fieldName(fieldNamePrefix,
entry.getKey());
Object value = entry.getValue();
if (value == null) {
newRecord.put(fieldName(fieldNamePrefix, entry.getKey()),
null);
return;
}
PROPOSED VERSION:
for (Map.Entry<String, Object> entry : originalRecord.entrySet()) {
final String fieldName = fieldName(fieldNamePrefix,
entry.getKey());
Object value = entry.getValue();
if (value == null) {
newRecord.put(fieldName(fieldNamePrefix, entry.getKey()),
null);
continue;
}

KAFKA-5967 Ineffective check of negative value in
CompositeReadOnlyKeyValueStore#approximateNumEntries()
long total = 0;
for (ReadOnlyKeyValueStore<K, V> store : stores) {
total += store.approximateNumEntries();
}
return total < 0 ? Long.MAX_VALUE : total;
The check for negative value seems to account for wrapping. However,
wrapping can happen within the for loop. So the check should be performed
inside the loop.
