As Milvus does not support adding fields by default, I need to export all data, move it to the new collection, and set it in the collection of dynamic fields. My plan is to export all data and then insert it, but how do I export it? I use query, but I keep encountering the 16384 limit. My primary key is in string format, so I cannot use the interval method.
on 2.6 add field is exported
you can use iterator to export your data out
you can also use VTS tool help you to do this
