1. We need to provide an another method to load an onnx model to db from a local directory, not from a db directory.
2. I see 'embedAll' and 'embedTexts', both handle plural cases, any function for a single case, e.g query text?
3. Also, why the class name has 'Model' at the end, e.g. 'OracleEmbeddingModel'?

1. I think load_onnx_model only accepts from a DB directory alias?

We could internally create a DB directory alias to load from any path but I believe the path would have to be on the server

2. We extend from DimensionAwareEmbeddingModel so we just need to define embedAll. In the test there is a singular version which then calls embedAll.

   Response<Embedding> resp = embedder.embed("hello world");
   assertThat(resp.content().dimension()).isGreaterThan(1);
   
   TextSegment segment = TextSegment.from("hello world");
   Response<Embedding> resp2 = embedder.embed(segment);
   assertThat(resp2.content().dimension()).isGreaterThan(1);
   
   List<TextSegment> textSegments = new ArrayList<>();
   textSegments.add(TextSegment.from("hello world"));
   textSegments.add(TextSegment.from("goodbye world"));
   textSegments.add(TextSegment.from("1,2,3"));
   Response<List<Embedding>> resp3 = embedder.embedAll(textSegments);

3. This is their naming convention to end in EmbeddingModel like LanguageModel
