Re: What happens when persistent outrigger gets full

You may find such with GigaSpaces. Here are some of them:
- Ability to control JavaSpace max # of entries 
- Ability to evict entries based on JVM available memory
- Ability to evict entries based on LRU policy
- Ability to use indexed file as persistent media and recover from this file
- Ability to cache data at the client side and sync with space 
- Ability to partition the space data into multiple physical spaces
- Scalable iterator that reads data from the space in batches to reduce
space and client JVM memory consumption
- Special Entry interface that optimize network traffic and memory usage
IExternalizable
- No Serialization mode which reduce the amount of memory used to store
entries with user defined attributes within the space and transport the
entries much faster when wrapped with MarshalledObject.

Please note all these are available with Gigaspaces community edition that
can be downloaded from:

Subject: Re: What happens when persistent outrigger gets full

Hi,

is there any data structure being used for the management of the
objects in the javaspace i.e. for the management of the Javaspace
memory or is it a simple dump of unordered data into the javaspace.

effective memory management ,replication  and caching would defintely
improve the performance and reliability of the space over a period of
time
