Constructor Detail

OffHeapDiskStoreConfiguration

public OffHeapDiskStoreConfiguration(int diskSegments)

Creates a new configuration instance using the provided diskSegments. Other attributes are set to their default (null for threadPoolAlias and DEFAULT_WRITER_CONCURRENCY for writerConcurrency).

Parameters:

diskSegments - number of disk segments allocated. The more disk segments there is, the more concurrency you get but the more resources you are using (mainly file pointers)

OffHeapDiskStoreConfiguration

public OffHeapDiskStoreConfiguration(java.lang.String threadPoolAlias,
                                     int writerConcurrency)

Creates a new configuration instance using the provided parameters. diskSegments is set to DEFAULT_DISK_SEGMENTS.

Parameters:

threadPoolAlias - the thread pool alias

writerConcurrency - the writer concurrency
