The presentation introduces the upcoming Document Server feature for InterSystems Cloud Document, a schemaless JSON database with SQL access. The new system uses two key innovations: Pack Vector Array (PVA): a compact, binary format for fast and efficient storage and retrieval and Common Key Map, which stores shared field names only once across similar documents. Together, these features significantly reduce storage size (up to 90% for deeply nested data) and improve query performance by enabling direct field access and faster indexing. This approach is especially useful for large, flexible datasets like medical records, offering both speed and efficiency in cloud document storage.
