Jonathan Ellis updated CASSANDRA-5486:
--------------------------------------
Description:
Inspecting the read path for CASSANDRA-4180 reveals several bugs introduced by
index promotion. Most fall into two categories:
# Conflating RowIndexEntry.isIndexed with hasPromotedIndex (if the latter is
true, we need to include its deletion info, even if there are no index entries,
which is what the former refers to)
# Incorrectly assuming RowIndexEntry.deletionInfo is the entire DeletionInfo
for the row, when it really only includes range tombstones

index promotion. Most fall into two categories:
# Incorrectly assuming that hasPromotedIndexes implies that the bloom filter is
not present in the data file either
# Incorrectly assuming RowIndexEntry.deletionInfo is the entire DeletionInfo
for the row, when it really only includes range tombstones
> bugs with index promotion and deletionInfo
