Unfortunately, we can’t prepare a server with such a large memory size at this time. Since I assume this issue is not related to the number of dimensions, I tested...
This time, the QG index involves an extremely large dataset, which seems to have caused read/write issues due to the large I/O size to the disk. It appears to depend...
The memory usage is higher than expected, but QG uses significantly more memory than graph and QBG.
This fix has been released as [v2.3.15](https://github.com/yahoojapan/NGT/releases/tag/v2.3.15).
Is it possible that you submitted this issue to the wrong repository?
I agree that metadata filtering is an important feature, but there are no concrete plans for it at the moment. If there is enough demand, we will consider implementing it....
In general, the time required for each insertion tends to gradually increase. This is because a search is performed during insertion, and as the number of inserted items increases, the...
When L2 is specified, NGT uses the following L2 distance to construct the ANNG. ```math \| \mathbf{x} \|_2 = \sqrt{ \sum_{i=1}^{n} x_i^2 } ``` The specified distance is always used.
The reason is quite simple: the L2 norm without the square root is no longer a true metric. In a graph, the connectivity between nodes must fundamentally be constructed based...
Whether NGT supports AVX2 or AVX-512 depends on which of those is supported by the CPU used during the build. If you want to disable AVX-512 on a CPU that...
