Feb 1, 2025Feb 2025 saw notable progress in stargate/data-api with substantial feature deliveries and robustness improvements. Key features include: improved path handling and escaping for JSON API and indexing (dots and ampersands in field names; robust path parsing across filters, sorts, projections); centralized naming rules with extended index naming length to 100 characters, improving governance and consistency; environment/runtime updates achieving security and performance gains (DSE 6.9.7 in Docker Compose and OpenJDK 21 across profiling/runtime images). A critical bug fix was implemented for the Data Vectorizer, preventing data insertions when multiple, differing vectorize configurations were present, introducing a new error code to clearly communicate vectorization configuration conflicts. Overall, these changes reduce runtime errors, improve data modeling consistency, and enhance deployment stability, delivering measurable business value in reliability, governance, and performance.
