allComponents

public Set<Component> allComponents()

Description copied from interface: SSTableFormat

All the components that the writter can produce when saving an sstable, as well as all the components that the reader can read.

primaryComponents

public Set<Component> primaryComponents()

batchComponents

public Set<Component> batchComponents()

Description copied from interface: SSTableFormat

Returns components required by offline compaction tasks - like splitting sstables.

uploadComponents

public Set<Component> uploadComponents()

Description copied from interface: SSTableFormat

Returns the components which should be selected for upload by the sstable loader.

mutableComponents

public Set<Component> mutableComponents()

Description copied from interface: SSTableFormat

Returns a set of the components that can be changed after an sstable was written.

generatedOnLoadComponents

public Set<Component> generatedOnLoadComponents()

Description copied from interface: SSTableFormat

Returns a set of components that can be automatically generated when loading sstable and thus are not mandatory.

getKeyCacheValueSerializer

public SSTableFormat.KeyCacheValueSerializer<BigTableReader,RowIndexEntry> getKeyCacheValueSerializer()

getScrubber

public IScrubber getScrubber(ColumnFamilyStore cfs,
 LifecycleTransaction transaction,
 OutputHandler outputHandler,
 IScrubber.Options options)

Description copied from interface: SSTableFormat

Returns a new scrubber for an sstable. Note that the transaction must contain only one reader and the reader must match the provided cfs.

getFormatSpecificMetricsProviders

public MetricsProviders getFormatSpecificMetricsProviders()

deleteOrphanedComponents

public void deleteOrphanedComponents(Descriptor descriptor,
 Set<Component> components)

delete

public void delete(Descriptor desc)

Description copied from interface: SSTableFormat

Deletes the existing components of the sstables represented by the provided descriptor. The method is also responsible for cleaning up the in-memory resources occupied by the stuff related to that sstables, such as row key cache entries.
