JSON and Metadata Filtering in Milvus

JSON, or JavaScript Object Notation, is a flexible data format used for storage and transmission. It employs key-value pairs adaptively, making it ideal for NoSQL databases and API results. Milvus Client, a wrapper around the Milvus collection object, uses a flexible JSON "key":value format to allow schema-less data definitions. This makes it faster and less error-prone than defining a full schema upfront. The schema-less schema includes fields for id (str) and vector (str), with the rest of the fields determined flexibly when the data is inserted into Milvus. JSON data can be uploaded directly into Milvus, which also supports metadata filtering on JSON fields and JSON array data types.
