    • Affects Version/s: 3.0.1

      Node v8.9.4

      Problem:
      bulk's final batch size is NOT sum of all document's bson-size, because batch query is an array, which add additional 4 bytes to each document.

      Example from real use-case
      According to unordered.js:188:
      _self.s.currentBatch.sizeBytes == 16776523

      According to commands.js:141:
      var query = self.bson.serialize(this.query,

      { checkKeys: this.checkKeys, serializeFunctions: this.serializeFunctions, ignoreUndefined: this.ignoreUndefined }

      )
      query.length == 16802161

      Thus, batch fails
