INDEX MAINTENANCE operation

I am just curious to know what this operation (INDEX MAINTENANCE) that I have never seen before stand for?

SQL Plan Monitoring Details (Plan Hash Value=1129128534)

=========================================================================================================================

| Id    |              Operation               |           Name           |  Rows   | Cost |   Time    | Start  | Execs |

|       |                                      |                          | (Estim) |      | Active(s) | Active |       |

=========================================================================================================================

|     0 | MERGE STATEMENT                      |                          |         |      |           |        |    17 |

|     1 |   PX COORDINATOR                     |                          |         |      |           |        |    17 |

|     2 |    PX SEND QC (RANDOM)               | :TQ10006                 |      1G |   4M |           |        |       |

|     3 |     INDEX MAINTENANCE                | THIS_IS_A_HEAP_TABLE     |         |      |           |        |       |

Is it simply saying that is it filling up the THIS_IS_A_HEAP_TABLE table indexes (only one index which is the PK index)?

Thanks

Mohamed Houri
