Apache Pinot

Hi team, I have a general query. Given schema, total no of rows in Pinot table and some cardinality information per column, I wanted to see how much will be approximate Pinot table size on disk.

Because its a columnar format, I was thinking
```if dictionary enabled:
    add dict size + (cardinality * max length/bytes)
if not
   take actual bytes for storage(eg 4 for int/ 8 for long etc) * no of rows```
Is there something I am missing?

```add dict size + (cardinality * max length/bytes)```
This is not correct

byte size of fwd index bit encoded = (numbits * numDocs) / 8 +
byte size of dictionary = cardinality * length (fixed or var)

Yes, as Sid mentioned, it is bit encoded. But you can get that from cardinality too.
