TimeoutException when adding new vertices during waitForIDBlockGetter

[amcp]

Hi Ingo, are you using the Gremlin Server zip we provide, or are you just using the Maven dependency in your own application? I just did a test of the server zip and I was able to write a vertex without timeouts.

I use the latest version of the dependency from Maven central. I will try to create a reproducible example. Everything works fine on DynamoDB local. But when I am deploying this and running against real DynamoDB it fails sometimes when adding vertices concurrently.

@amcp would you expect this when running out of read/write provisioning? This was happening on a table that was only provisioned at 1 r/w unit. And CloudWatch showed that my test used exactly 100% of the read provisioning.

Seems likely that increasing the read/write capacity of the table in question would solve the problem. From the stack trace, I suspect the titan_ids table is the one that needs more provisioned IOPS. Could you try and report back please?

[ingojaeckel]

I will close this as I have not seen this anymore after increasing provisioning on titan_ids and other tables.
