機能

  • Added global database load balancing with low latency.
    • Intelligently routes edge application queries for the Amazon Aurora Global Database by choosing the optimal reader instance and caching at the edge.
    • Improves response times and availability while automating Amazon RDS management for lower TCO (total cost of ownership).
  • Added integration with and support for Amazon RDS Global databases for auto failover.
  • Added support for latency based reader selection in multi-az and region configurations.
  • Added metrics to track jvm heap allocation rate and hiccups.
  • Updated RHEL install logic for newer Redhat versions.
  • Added synchronization of TLS certificates so all proxies will use the same certificate and updated TLS certificate management documentation.
  • Added a knob to enable TLS 1.0 and 1.1 for older drivers that don’t support TLS 1.2+.
  • Added significant improvements to the Cloudformation template to make it more flexible and cover more customer environment configurations.
  • Improved DNS redirection mode by adding the ability to redirect to AWS (Amazon Web Services) public IP, not just private.
  • Added the ability to download drivers from Maven central to avoid packaging the MySQL driver for legal reasons.
  • Improved documentation for heimdall sync user functionality.
  • Disabled vdbs will now be put at the bottom of the status tab.
  • Improved Postgres copy support.
  • Removed the “track” option from the admin software tab, now alerts will only be for release versions.
  • Alerts added if the cache client isn’t ready.
  • Added support to cache MySQL stored procedure calls (they require a table attribute before cache will work).
  • Added additional tooltip info for servers on the info tab.
  • Added 1GB of swap space by default to AWS (Amazon Web Services) images to help avoid out of memory situations.
  • Improved nocache reasons, including the ability to report multiple reasons at once.
  • Improved compatibility with all database protocol types.
  • Added the ability to detect when binary values are used for primary key inserts and handle it properly when using client-side prepares at the driver level for MySQL.
  • Adjusted images so that initial console logging can be observed with “journalctl -u heimdall.service”.
  • Added huge improvements in test infrastructure to improve regression coverage.
