NULL, or the next index whose record should be handled
| btr_pcur_t purge_node_t::pcur |
persistent cursor used in searching the clustered index record
| dtuple_t* purge_node_t::ref |
NULL, or row reference to the next row to handle
| dtuple_t* purge_node_t::row |
NULL, or a copy (also fields copied to heap) of the indexed fields of the row to handle
| dict_table_t* purge_node_t::table |
table where purge is done
| ib_vector_t* purge_node_t::undo_recs |
Undo recs to purge
