Samarth Jain commented on PHOENIX-2896:
---------------------------------------
[~tdsilva] - I am not sure I understood your question. We use the default
family name for tracking column qualifier counters for mutable tables.
{code:java}
if (immutableStorageScheme == SINGLE_CELL_ARRAY_WITH_OFFSETS && encodingScheme
!= NON_ENCODED_QUALIFIERS) {
// For this scheme we track column qualifier counters at the column family
level.
cqCounterFamily = colDefFamily != null ? colDefFamily : (defaultFamilyName !=
null ? defaultFamilyName : DEFAULT_COLUMN_FAMILY);
} else {
// For other schemes, column qualifier counters are tracked using the default
column family.
cqCounterFamily = defaultFamilyName != null ? defaultFamilyName :
DEFAULT_COLUMN_FAMILY;
}{code}
> Support encoded column qualifiers per column family
