Ingest sst file does not overwrite the old data

[Nicole00]

After the SST file was imported through INGEST, it doesn't overwrite the data that was previously inserted.

operations：

1. Insert a point data: insert vertex user(name) values ​​1:("tom")
2. Generate sst based on csv file, csv has only two records of data: (the first col is vid, the second col is name)

1, jina
2, tina

3. After INGEST is imported, the show stats shows two records, and the vertex with id 2 can be found through the fetch statement. The name of the vertex with id 1 is still tom, which has not been overwritten with jina.

extra info：
version： 2.5.0 rpm

I have try to replay this case, but it didn't happen.

First, insert some vertex into the database and then ingest an SST file. I can read the new value created by ingest file.

you should set enable_vertex_cache is false to make sure ingest SST file into system

I think this should be documented/highlighted in SST chapters

It is only updated in 2.5.0 and 2.5.1 branch, because the parameter enable_vertex_cache has not been available since 2.6.

Sorry, I didn't realize it's already there, thanks!!!
