Vudojind You may need to combine more than one doocumentation the sets of instructions. From that point on, you manage the cache through API calls in your application. The schema definition file is available at http: See the Javadocs for org. The cache also provides features like transactions, data querying, disk storage management, and logging. VMware vFabric — Pivotal GemFire Documentation To aid in the administration of cache data and speed documetation setup of new environments, you can export a snapshot of the entire cache all regions and then import the snapshot into a new cache. For more details on exporting and importing snapshots of a cache, see Cache and Region Snapshots.

The actual concurrency will vary. Ideally, you should choose a value to accommodate as many threads as will ever concurrently modify values in the region. Using a significantly higher value than you need can waste space and time, and a significantly lower value can lead to thread contention. But overestimates and underestimates within an order of magnitude do not usually have much noticeable impact.
A value of one is appropriate when it is known that only one thread will modify and all others will only read. This can cause operations to be conflated, so that some cache listeners may see an event while others do not, but it guarantees that the system will be consistent.
The default is to look for and join JTA transactions for operations performed on a region. DiskStoreName [default: null, meaning no disk store] If not null then this region will write its data to the named DiskStore. String RegionAttributes.
This means that they will be in the file system buffer before the operation doing the write returns. If false then any writes to disk done for this region will be done asynchronously. Asynchronous writes will be conflated if the same entry is written while a previous operation for the same entry is still in the queue.
