feature(StoneDB 8.0): 'bool partitioned' parameter is added by MySQL 8.0 in handlerton->create function

[DandreChen]

Is your feature request related to a problem? Please describe.

handlerton->create function function add "bool partitioned" parameter, in tianmu as below:

handler *rcbase_create_handler(handlerton *hton, TABLE_SHARE *table, bool partitioned, MEM_ROOT *mem_root) 

Describe the solution you'd like

adapt the code for MySQL 8.0

Describe alternatives you've considered

Additional context

[lujiashun]

From the create functions of storage engines as below, we can see that the partitioned value is only used by innodb, others ignore the partitioned argument.
innodb is row_based, and support partition feature to split rows into partitions;
tianmu is column_based, now unsupport partition feature. Maybe we can support it in some day,eg, split rows in partitions,
and columns of row belongs to different partitions should not be stored together in one DPN,etc.

innobase storage

static handler *innobase_create_handler(handlerton *hton, TABLE_SHARE *table,
                                        bool partitioned, MEM_ROOT *mem_root) {
  if (partitioned) {
    ha_innopart *file = new (mem_root) ha_innopart(hton, table);
    if (file && file->init_partitioning(mem_root)) {
      destroy(file);
      return (nullptr);
    }
    return (file);
  }

  return (new (mem_root) ha_innobase(hton, table));
}

myisam storage

static handler *myisam_create_handler(handlerton *hton, TABLE_SHARE *table,
                                      bool, MEM_ROOT *mem_root) {
  return new (mem_root) ha_myisam(hton, table);
}

archive storage

static handler *archive_create_handler(handlerton *hton, TABLE_SHARE *table,
                                       bool, MEM_ROOT *mem_root) {

}

blackhole storage

  return new (mem_root) ha_blackhole(hton, table);
}

federated storage

static handler *federated_create_handler(handlerton *hton, TABLE_SHARE *table,

}

heap storage

static handler *heap_create_handler(handlerton *hton, TABLE_SHARE *table, bool,

  return new (mem_root) ha_myisammrg(hton, table);
}

tina storage

static handler *tina_create_handler(handlerton *hton, TABLE_SHARE *table, bool,
                                    MEM_ROOT *mem_root) {
  return new (mem_root) ha_tina(hton, table);
