3. Where can I learn about the latest releases of Numaflow?

4. I see Server Info File not ready log in the numa container. What does this mean?

This message indicates that the server has not started yet. Common reasons include:

  • The server was not started correctly in the udcontainer.
  • The server is still initializing (for example, the application code is downloading cache files or performing setup tasks).

5. What is partitions in Numaflow?

The field partitions is the number of streams between the vertices. Larger the parition number, higher the TPS that vertex can take. Note that partitions are owned by the vertex reading the data, to create a multi-partitioed edge we need to configure the vertex reading the data to have multiple partitions.
