Use OpenAIEmbeddings() once and then re-recreate MemoryVectorStore?

[bennofatius]

In my test app I'm running below step before every chain call which always takes time and feels unnecessary. I assume that I could instead turn my context into embeddings only once, and then use the resulting data to re-create a MemoryVectorStore in the future? If so, how do I do that?

const newVectorStore = await MemoryVectorStore.fromDocuments(doc, new OpenAIEmbeddings()
