com.gemstone.gemfire.cache.snapshot
Provides API's for importing and exporting cached data into snapshot files.
Each snapshot file contains the cache entries (key/value pairs) for a given
region.
The {@link com.gemstone.gemfire.cache.snapshot.RegionSnapshotService} can be
obtained for an individual region using
{@link com.gemstone.gemfire.cache.Region#getSnapshotService}. To obtain a
{@link com.gemstone.gemfire.cache.snapshot.CacheSnapshotService} (across all
regions), invoke {@link com.gemstone.gemfire.cache.Cache#getSnapshotService}.
The {@link com.gemstone.gemfire.cache.snapshot.SnapshotOptions} can be used to
configure the behavior of import and export operations.
The {@link com.gemstone.gemfire.cache.snapshot.SnapshotReader} can be used to
programmatically read a snapshot created using the GEMFIRE
{@link com.gemstone.gemfire.cache.snapshot.SnapshotOptions.SnapshotFormat}
format.
Example usage:
// obtain the snapshot service
RegionSnapshotService snapshot = region.getSnapshotService();
// export the region
snapshot.save(new File("myregion.snapshot"), SnapshotFormat.GEMFIRE);
// import the data
snapshot.load(new File("myregion.snapshot"), SnapshotFormat.GEMFIRE);
