Interface StoreParamsDynamic

All Known Implementing Classes:
StoreParams
public interface StoreParamsDynamic
Store parameters that can be adjusted after a store has been created, and given different values when the JVM attaches to a store area. (They are still fixed for any given database once created in a JVM.)

  • Method Details

    • getFileMode

      FileMode getFileMode()
      Store-wide file access mode

    • isSetFileMode

      boolean isSetFileMode()

    • getBlockReadCacheSize

      Integer getBlockReadCacheSize()
      Block read cache (note: mapped files do not have a block cache)

    • isSetBlockReadCacheSize

      boolean isSetBlockReadCacheSize()

    • getBlockWriteCacheSize

      Integer getBlockWriteCacheSize()
      Block write cache (note: mapped files do not have a block cache)

    • isSetBlockWriteCacheSize

      boolean isSetBlockWriteCacheSize()

    • getNode2NodeIdCacheSize

      Integer getNode2NodeIdCacheSize()
      Node cache for Node->NodeId.

    • isSetNode2NodeIdCacheSize

      boolean isSetNode2NodeIdCacheSize()

    • getNodeId2NodeCacheSize

      Integer getNodeId2NodeCacheSize()
      Node cache for NodeId->Node. Important for SPARQL results.

    • isSetNodeId2NodeCacheSize

      boolean isSetNodeId2NodeCacheSize()

    • getNodeMissCacheSize

      Integer getNodeMissCacheSize()
      Node cache for recording known misses

    • isSetNodeMissCacheSize

      boolean isSetNodeMissCacheSize()

    • getNodeCacheInitialCapacityFactor

      Double getNodeCacheInitialCapacityFactor()
      Initial capacity factor for node caches:
      • if >= 0.0: initial capacity is set to the (maximum) size of the cache multiplied by the factor
      • if < 0.0: no initial capacity is set on the cache, i.e. its internal default is used

    • isSetNodeCacheInitialCapacityFactor

      boolean isSetNodeCacheInitialCapacityFactor()
