DumpConsumer (Ignite 2.17.0)

All Known Implementing Classes:

JsonDumpConsumer
```
public interface DumpConsumer
```
Consumer of a cache dump. This consumer will receive all DumpEntry stored in cache dump during IgniteDumpReader application invocation. The lifecycle of the consumer is the following:
- Start of the consumer start().
- Stop of the consumer stop().

- Method Detail
  - start
```
void start()
```
    Starts the consumer.
  - onMappings
```
void onMappings(Iterator<TypeMapping> mappings)
```
    Handles type mappings.
    
    Parameters:
    
    mappings - Mappings iterator.
  - onTypes
```
void onTypes(Iterator<BinaryType> types)
```
    Handles binary types.
    
    Parameters:
    
    types - Binary types iterator.
  - onCacheConfigs
```
void onCacheConfigs(Iterator<org.apache.ignite.internal.processors.cache.StoredCacheData> caches)
```
    Handles cache configs. Note, there can be several copies of cache config in the dump. This can happen if dump contains data from several nodes.
    
    Parameters:
    
    caches - Stored cache data.
  - onPartition
```
void onPartition(int grp,
                 int part,
                 Iterator<DumpEntry> data)
```
    Handles cache data. This method can be invoked by several threads concurrently. Note, there can be several copies of group partition in the dump. This can happen if dump contains data from several nodes. In this case callback will be invoked several time for the same pair of [grp, part] values.
    
    Parameters:
    
    grp - Group id.
    
    part - Partition.
    
    data - Cache data iterator.

    DumpReaderConfiguration.threadCount()
  - stop
```
void stop()
```
    Stops the consumer. This method can be invoked only after start().
