java.lang.Object
org.eclipse.jgit.internal.storage.dfs.DfsBlockCacheConfig.DfsBlockCachePackExtConfig

A configuration for a single cache table storing 1 or more Pack extensions.

The current pack ext cache tables implementation supports the same parameters the ClockBlockCacheTable (current default implementation).

Configuration falls back to the defaults coded values defined in the DfsBlockCacheConfig when not set on each cache table configuration and NOT the values of the basic dfs section.

Format: [core "dfs.packCache"] packExtensions = "PACK" blockSize = 512 blockLimit = 100 concurrencyLevel = 5 [core "dfs.multipleExtensionCache"] packExtensions = "INDEX REFTABLE BITMAP_INDEX" blockSize = 512 blockLimit = 100 concurrencyLevel = 5
