Variants§
None
A sentinel that indicates there were no elements.
Mixed
There were elements from more than one category of: bools, strings, numerics, lists, maps.
JsonNulls
A sentinel that indicates all elements were Datum::JsonNull
s.
Bools(PrimitiveStats<bool>)
The min and max bools, or None if there were none.
Strings(PrimitiveStats<String>)
The min and max strings, or None if there were none.
Numerics(PrimitiveStats<Vec<u8>>)
The min and max numerics, or None if there were none. Since we don’t have a decimal type here yet, this is stored in serialized form.
Lists
A sentinel that indicates all elements were Datum::List
s.
TODO: We could also do something for list indexes analogous to what we do for map keys, but it initially seems much less likely that a user would expect that to work with pushdown, so don’t bother keeping the stats until someone asks for it.
Maps(BTreeMap<String, JsonMapElementStats>)
Recursive statistics about the set of keys present in any maps/objects in the column, or None if there were no maps/objects.
