Hi,

Unfortunatelly ignite does not support keepBinary option for Maps [1].
Best way is try to avoid using short-lived Maps.

But you can try to implementation of BinaryObject that implements 
Externalizable interface where you will free to choose the way to access map 
entries.
For example, such implementation can have BinaryObject.field() method with same 
semantic as Map.get() method.

Hi Andrey,

Thanks for your response. Is there a way I can disable it or reduce it? Do I 
need to use BinaryObject?

Thanks,

Hi

As I understand you have many short-lived Maps as values in cache.
Yes, in your case, you can get a lot of garbage due to Map will be 
marshal\unmarshal along with each of its content at every cache entry access.

Hi,

I have an application which uses apache ignite cache in an embedded mode. On 
each GC cycle, I am seeing lot of memory getting retained. Cache has around 10K 
entries and each entry is an object containing a map of 500 entries. The key 
and value in the map within an object is string of less than 20 bytes.

I see lot of time spent during the marshalling process when the cache entry is 
made.

Does ignite generate lot of short lived objects during the marshalling process? 
What would cause lot of memory to be retained during each GC cycle?

Thanks,
Pradeep V.B.
