Hi Navneet,

My understanding is that after calling bulkInsertTuples, 
bulkInsertTuplesWithRemappedAttributes or insertTupleInBatch, the consistency 
of the block is broken and the index will not work until rebuild() is called. 
Thus any operation based on index or tuple order will not be safe.


Hope that others could give a more detailed explanation. :)

Subject: Warning in TupleStorageSubBlock.hpp

Hi Quicksteppers
I just came across this warning in the documentation for 
TupleStorageSubBlock::bulkInsertTuples and 
bulkInsertTuplesWithRemappedAttributes functions. Can someone explain what it 
means?
Cheers,
Nav

   * @warning The inserted tuples may be placed in an "incorrect" or
   *          sub-optimal locations in this TupleStorageSubBlock. The only
   *          methods which are safe to call between bulkInsertTuples() and
   *          rebuild() are insertTupleInBatch(), bulkInsertTuples(), and
   *          bulkInsertTuplesWithRemappedAttributes().
