Method Detail

selectDirtyINsForCheckpoint

void selectDirtyINsForCheckpoint(Set mustSyncSet)
                           throws DatabaseException

Scan the INList for all dirty INs, excluding deferred write INs that are not in the must-sync set. Save them in a tree-level ordered map for level ordered flushing. Take this opportunity to reset the memory budget tree value.

Throws:

DatabaseException

selectDirtyINsForDb

void selectDirtyINsForDb(DatabaseImpl dbImpl)
                   throws DatabaseException

Scan the INList for all dirty INs for a given database. Arrange them in level sorted map for level ordered flushing.

Throws:

DatabaseException

getNumLevels

int getNumLevels()

getHighestLevel

int getHighestLevel()

addCostToMemoryBudget

void addCostToMemoryBudget()

removeCostFromMemoryBudget

void removeCostFromMemoryBudget()

addDirtyIN

void addDirtyIN(IN in)

Add a node to the dirty map. The dirty map is keyed by level (Integers) and holds sets of IN references.

getLowestLevelSet

Integer getLowestLevelSet()

Get the lowest level currently stored in the map.

getSet

Set getSet(Integer level)

Get the set corresponding to this level.

removeSet

void removeSet(Integer level)

Get the set corresponding to this level.
