Vector Databases

Vector databases are designed to efficiently handle vector data, which is prevalent in scenarios like embeddings generated by neural networks, feature vectors representing data points, and more. These databases often employ techniques such as indexing and search algorithms that are specifically tailored to work well with vector spaces. 

Here are some notable ones:

  1. Faiss:


    • Description: Faiss (Facebook AI Similarity Search) is an open-source library for efficient similarity search and clustering of dense vectors.
    • Link: Faiss GitHub Repository

  2. Milvus:


    • Description: Milvus is an open-source vector database designed for handling large-scale vector data. It is often used for similarity search and recommendation systems.
    • Link: Milvus GitHub Repository

  3. Annoy:


    • Description: Annoy is a C++ library with Python bindings for approximate nearest neighbors in high-dimensional spaces.
    • Link: Annoy GitHub Repository

  4. Elasticsearch with Vector Similarity Plugin:


    • Description: Elasticsearch is a widely used search and analytics engine. The Vector Similarity Plugin allows Elasticsearch to handle vector data and perform similarity searches.
    • Link: Vector Similarity Plugin GitHub Repository

  5. HNSW (Hierarchical Navigable Small World Graph):


    • Description: HNSW is a data structure and algorithm for approximate similarity search. It's often used in building vector databases for efficient nearest-neighbor search.
    • Link: HNSW GitHub Repository

Please note that the status, features, and popularity of these databases may have changed since my last update, and there may be new developments or databases introduced since then. Always refer to the respective repositories or official documentation for the latest information.

What is Tensor Parallelism and relationship between Buffer and GPU

  Tensor Parallelism in GPU Tensor parallelism is a technique used to distribute the computation of large tensor operations across multiple GPUs or multiple cores within a GPU .   It is an essential method for improving the performance and scalability of deep learning models, particularly when dealing with very large models that cannot fit into the memory of a single GPU. Key Concepts Tensor Operations : Tensors are multidimensional arrays used extensively in deep learning. Common tensor operations include matrix multiplication, convolution, and element-wise operations. Parallelism : Parallelism involves dividing a task into smaller sub-tasks that can be executed simultaneously. This approach leverages the parallel processing capabilities of GPUs to speed up computations. How Tensor Parallelism Works Splitting Tensors : The core idea of tensor parallelism is to split large tensors into smaller chunks that can be processed in parallel. Each chunk is assigned to a different GP...

What's replicated, what's not?

Logged operations are replicated. These include, but are not limited to: DDL DML Create/alter table space Create/alter storage group Create/alter buffer pool XML data. Logged LOBs Not logged operations are not replicated. These include, but are not limited to: Database configuration parameters (this allows primary and standby databases to be configured differently). "Not logged initially" tables Not logged LOBs UDF (User Defined Function) libraries. UDF DDL is replicated. But the libraries used by UDF (such as C or Java libraries)  are not replicated, because they are not stored in the database. Users must manually copy the libraries to the standby. Note: You can use database configuration parameter  BLOCKNONLOGGED  to block not logged operations on the primary.
