示例1: checkCollectionIndexes

  async checkCollectionIndexes(coll:Collection): Promise<any> {
    const indexes = this.getIndexes();
    if (indexes && indexes.length) {
      let currIndexes;
      try {
        currIndexes = await coll.indexes();
      } catch(e) {
        currIndexes = [];
      }
      for (let i of indexes) {
        const props = [ 'unique', 'sparse', 'min', 'max', 'expireAfterSeconds', 'key' ];

        let c_i = currIndexes.find(t => {
          return (typeof i.name === 'undefined' || i.name === t.name) && _.isEqual(_.pick(i, props), _.pick(t, props));
        });
        if (!c_i) {
          if (this.createIndexes) {
            logger.info(this.name, 'creating missing index', i);
            await coll.createIndex(i.key, _.omit(i, 'key'));
          } else {
            logger.warn(this.name, 'missing index', i);
