Known Limitations
Delay on DDL Requests
DDL requests, such as CREATE TABLE, take a few seconds each to complete. Because of that, large database initialization scripts may take longer than expected. This will be addressed in an upcoming release.
Performance of GridGain 8 Applications
Some scenarios may see lower performance when moving to GridGain 9. This is a temporary limitation, and the performance in these scenarios will be improved in upcoming versions.
High-Availability with Two Data Copies
When a partition loses majority of its copies, it becomes unavailable. This behavior is required for split-brain protection. Because of this, in a distribution zone with 2 data replicas, losing one node may lead to partial unavailability.
To achieve both split-brain protection and full availability with one node down, use 3 or more replicas.
Upcoming versions will add a high-availability mode that support full availability with one node down when using 2 replicas.
Data Center Replication with Multiple Data Centers
Complex Data Center Replication topologies (for example, the ones involving cycles) of 3 or more data centers are not supported. This will be addressed in an upcoming release.
