public CFMetaData.Builder metadataBuilder()
{
CFMetaData.Builder builder = CFMetaData.Builder.create(keyspace(), columnFamily(), isDense, isCompound, hasCounters);

for (int i = 0; i < keyAliases.size(); i++)
builder.addPartitionKey(keyAliases.get(i), keyTypes.get(i));
for (int i = 0; i < columnAliases.size(); i++)

boolean isStaticCompact = !isDense && !isCompound;
for (Map.Entry<ColumnIdentifier, AbstractType> entry : columns.entrySet())

}
boolean isCompactTable = isDense || !isCompound;

// Even for dense, we might not have our regular column if it wasn't part of the declaration. If
// that's the case, add it but with a specific EmptyType so we can recognize that case later
builder.addRegularColumn(names.defaultCompactValueName(), EmptyType.instance);
}
