Description

Size of GridComponetns data may increase significantly in large deployment.

Examples:
1) In case of more then 3K caches with QueryEntry configured - size of DiscoveryDataBagGridCacheProcessor data bag consume more then 20 Mb
2) If cluster contain more then 13K objects - GridMarshallerMappingProcessor size more then 1 Mb
3) Cluster with more then 3К types in binary format - CacheObjectBinaryProcessorImpl size can grow to 10Mb

The data in most cases contain duplicated structure and simple zip compression can led to seriously reduce size.
