      • Tracker

        public Tracker​(ColumnFamilyStore columnFamilyStore,
               Memtable memtable,
               boolean loadsstables)
        Parameters:
        columnFamilyStore -
        memtable - Initial Memtable. Can be null.
        loadsstables - true to indicate to load SSTables (TODO: remove as this is only accessed from 2i)

    • Method Detail

      • dropSSTablesIfInvalid

        public java.lang.Throwable dropSSTablesIfInvalid​(java.lang.Throwable accumulate)

      • dropSSTables

        public void dropSSTables()

      • dropSSTables

        public java.lang.Throwable dropSSTables​(java.lang.Throwable accumulate)

      • dropSSTables

        public java.lang.Throwable dropSSTables​(com.google.common.base.Predicate<SSTableReader> remove,
                                        OperationType operationType,
                                        java.lang.Throwable accumulate)
        removes all sstables that are not busy compacting.

      • removeUnreadableSSTables

        public void removeUnreadableSSTables​(File directory)
        Removes every SSTable in the directory from the Tracker's view.
        Parameters:
        directory - the unreadable directory, possibly with SSTables in it, but not necessarily.

      • switchMemtable

        public Memtable switchMemtable​(boolean truncating,
                               Memtable newMemtable)
        Switch the current memtable. This atomically appends a new memtable to the end of the list of active memtables, returning the previously last memtable. It leaves the previous Memtable in the list of live memtables until discarding(memtable) is called. These two methods must be synchronized/paired, i.e. m = switchMemtable must be followed by discarding(m), they cannot be interleaved.
        Returns:
        the previously active memtable
