int NdbOptimizeTableHandleImpl::init ( Ndb *  ndb,
const NdbTableImpl &  table 
)

search whether there are var size columns in the table, in first step, we only optimize var part, then if the table has no var size columns, we do not do optimizing

Here is the caller graph for this function:

int NdbOptimizeTableHandleImpl::next ( void  )

Optimize one more batch of records

Returns
1 for more records left to optimize, 0 when completed -1 encountered some error

Get update operation

optimize a tuple through doing the update first step, move varpart

nextResult(false) means that the records cached in the NDBAPI are modified before fetching more rows from NDB.

Commit when all cached tuple have been updated
