   Thanks @doki23 
   
   I am curious, why do the record batches look like this? when i used `select 
distinct to_date(...) from t ` or `select to_date(...) as x from t group by x`?
   
   ```
   batch 1: []
   batch 2: []
   batch 3: []
   batch 4: []
   batch 5: []
   batch 6: []
   batch 7: [2012-04-27]
   batch 8: [2012-04-23, 2012-04-24]
   batch 9: [2012-04-25]
   batch 10: [2012-04-26]
   ```
   
   You would expect them to look something similar to this right?
   
   ```
   batch 1: [2012-04-27]
   batch 2: [2012-04-23]
   batch 3: [2012-04-24]
   batch 4: [2012-04-25]
   batch 5: [2012-04-26]
   ```
