CreateEmptyStripeBuffers in cstore_writer

[sri harsha]

  Hi ,

         In CreateEmptyStripeBuffers function in cstore_writer.c contains the following code snippet


ColumnBlockData **blockDataArray = palloc0(columnCount * sizeof(ColumnBlockData*));

ColumnBlockData *blockData = palloc0(sizeof(ColumnBlockData));
bool *existsArray = palloc0(blockRowCount * sizeof(bool));
Datum *valueArray = palloc0(blockRowCount * sizeof(Datum));

blockData->existsArray = existsArray;
blockData->valueArray = valueArray;
blockData->valueBuffer = NULL;
blockDataArray[columnIndex] = blockData;

             
         What is the significance of the above code block ?? blockDataArray created is not assigned anywhere in this function . Am i missing something ??

Thanks,
Harsha

Hi Harsha

It does not look like it is serving any purpose there. References to ColumnBlockData should be removed from there.
