Basic Concepts
Vectors
Vectors are arrays of numbers representing data points in a high-dimensional space. ChromaDB specializes in managing these vectors and performing operations such as similarity searches.
Collections
Collections are groups of vectors stored together in ChromaDB. They help organize and manage the data efficiently.
Indexes
Indexes in ChromaDB are data structures that allow for fast retrieval of vectors based on similarity measures.
