UnfilteredRowIterator	rowIterator(DecoratedKey key, Slices slices, ColumnFilter columnFilter, boolean reversed, SSTableReadsListener listener)	Returns a row iterator for the given partition, applying the specified row and column filters.

Method Detail

rowIterator

UnfilteredRowIterator rowIterator(DecoratedKey key,
                                  Slices slices,
                                  ColumnFilter columnFilter,
                                  boolean reversed,
                                  SSTableReadsListener listener)

Returns a row iterator for the given partition, applying the specified row and column filters.

Parameters:

key - the partition key

slices - the row ranges to return

columnFilter - filter to apply to all returned partitions

reversed - true if the content should be returned in reverse order

listener - a listener used to handle internal read events

rowIterator

default UnfilteredRowIterator rowIterator(DecoratedKey key)

partitionIterator

UnfilteredPartitionIterator partitionIterator(ColumnFilter columnFilter,
                                              DataRange dataRange,
                                              SSTableReadsListener listener)

Returns a partition iterator for the given data range.

Parameters:

columnFilter - filter to apply to all returned partitions

dataRange - the partition and clustering range queried

listener - a listener used to handle internal read events

getMinTimestamp

long getMinTimestamp()

Minimum timestamp of all stored data

getMinLocalDeletionTime

int getMinLocalDeletionTime()

Minimum local deletion time in the memtable
