Continuous Deployment support

[flang...@gmail.com]

Hi,

lets assume i have a stored procedure sp1 using table t1 in a cluster with 5 nodes.

I would like to understand migration concepts.

0. Is there any documentation regarding this topic. I did not find any.

1. Lets assume i need to make a change to sp1. How do i do a live migraton on all 5 nodes ? How is VoltDB handling this ?

Is VoltDB pausing the queue for these SP requests, updating the procedure and then continuing?

Any information on concepts/documentation regarding the support of the continuous deployment/delivery concept would be appreciated

Best

Frank

Hi Frank,

VoltDB will handle the atomic delivery of the new stored procedure to all nodes in the cluster.   See https://docs.voltdb.com/UsingVoltDB/sysprocupdateclasses.php for the method.

> Is VoltDB pausing the queue for these SP requests, updating the procedure and then continuing?

Yes, the update is a multi-partition transaction (across all partitions in the cluster).
