Instaclustr Observations• Continued stagnation of new committers being brought in - This is hard with
the 4.0 code freeze as feature work is considered an important step inbecoming a committer
• Cloud provider services (e.g. DynamoDB, Aurora) increasingly the preferencefor smaller startups, greenfield and teams. Fear of lock-in is very real thoughfor more sophisticated teams + OSS APIs become critical.
• Increasingly a DB of choice for large orgs building out a internal DBaaS Capability.

Summary• Still facing some challenges with project velocity
o Recent efforts in the road to 4.0 are likely to pay off significantly in making it easier to introduce and test new features
• Dominant with on-prem and companies looking to reduce risk of vendor lock-in
• Facing increasing pressure from cloud provider service offerings
• Next 6-12 months critical with the (potential) release of 4.0 for building back up velocity and interest in the project.
