There seems to be a bug in datax's extraction of mongodb data. You need to set the batchSize for each find(). Will cause memory overflow。

In MongodbReader, data is obtained through dbCursor = col.find(filter).iterator();, but the amount of data obtained in each batch is not set, which will cause memory overflow. Need to be modified like this： dbCursor = col.find(filter).batchSize(1000).iterator();
