The text discusses the limitations of NoSQL databases in handling complex queries, particularly analytics queries, and introduces SingleStoreDB as a distributed SQL database that can handle both analytical (OLAP) and transactional (OLTP) workloads in the same table type. It highlights the benefits of migrating from NoSQL to SingleStoreDB, including fast ingestion speed, high query performance, and support for JSON data formats. The text also compares two options for handling JSON arrays: importing them as fields in a JSON type or creating separate tables to represent the arrays. It notes that while the first option is faster, it has drawbacks such as losing table structure, whereas the second option provides more readable data schema but may impact ingest speed and join performance. Ultimately, SingleStoreDB offers a scalable solution for handling complex queries and data formats, making it an attractive alternative to legacy NoSQL databases.
