Deprecated. will be removed when it is assumed that the minimum upgrade-from-version is the version that this patch made it into

Used to serialize to an old version - needed to be able to update sstable level without a full compaction.

Parameters:

sstableStats -

legacyDesc -

out -

Throws:

java.io.IOException

deserialize

public Pair<SSTableMetadata,java.util.Set<java.lang.Integer>> deserialize(Descriptor descriptor)
                                                                   throws java.io.IOException

deserializes the metadata returns a pair containing the part of the metadata meant to be kept-in memory and the part that should not.

Parameters:

descriptor - the descriptor

Returns:

a pair containing data that needs to be in memory and data that is potentially big and is not needed in memory

Throws:

java.io.IOException
