Want to know some features of sptag

[frg01]

I would like to know about the features of sptag.

1. Does it support incremental indexing (that is, inserting data after the index is created successfully will update the index data)?

2. Does it support the creation of indexes for large data sets with low memory (for example: I only have 1G of memory, can I still create an index for 100 million, 1024-dimensional data?)
