does milvus is reindex everything

[vihariazure]

Hi Team,

I have a scenario where I initially inserted 1 million data points into a collection. After one day, I added another 1,000 records to the same collection. I would like to understand how reindexing works in this case:

Will the entire 1 million + 1,000 records be reindexed?
Will only the segments that receive the new data points be reindexed?
Or will no reindexing occur because the new records will go into a new segment?
Additionally, how does reindexing work in the case of updates to existing records?

milvus will rebuild data for incremental segments.

After you have enough incremental data, then compaction will be triggered and everything will be indexed.
