Predicate is being moved, please retry later

Retrying req: 23214. Error: rpc error: code = Unknown desc = failed to apply mutations error: internal error: rpc error: code = Unknown desc = Predicate is being moved, please retry later

I try to use a dgraph cluster, however, I noticed that after predicate balancing (approx 10mins into the ingestion) I often get the above error. Much appreciated if someone can share some light on this issue.

I thought the dgraph instances are able to communicate with each other about where the new location of the predicate, even though certain predicates have been moved from nodeA to nodeB.

The expected behavior:

node A serves predicate x
after 10 mins predicate x is moved to node B
ingestion still works when I try to ingest triples related to predicate x via grpc address of node A

Does the error message “Predicate is being moved, please retry later” get returned consistently even after retrying later?

The dgraph cluster won’t accept updates to that predicate while the move is in progress, but once the move has finished it should accept updates as normal. Depending on how large the data being moved is, this could take some minutes.

Retrying req: 1. Error: rpc error: code = Unavailable desc = grpc: the connection is unavailable

After a lot of retries, the grpc connection is closed.
Is there a configuration I can set to disable to predicate balancing? Or a workaround to this problem?

peter · October 31, 2017, 3:19am

That’s odd that the connection becomes unavailable. Did the dgraph instance crash? Do you have the output from the dgraph it is trying to connect to?

jzhu077 · October 31, 2017, 3:26am

all dgraph nodes have similar logs after the nomal logs i.e ask to serve certain predicates

I don’t see anything too strange in the logs near the predicate move. It doesn’t look like the dgraph instance crashed. What happens if you retry (with backoff) after getting the “unavailable” error code? According to the grpc standard, “unavailable” is transient. Perhaps the client/server implementations are putting the error in.

There’s not any way to tell the cluster not to try to balance predicates.

mrjn · October 31, 2017, 3:39am

We could easily add it so that Zero won’t try to rebalance the predicates, but that would just mean that the servers would be unbalanced – which would mean worse cache usage and overall slowness in running queries.

It’s better to understand if what you’re seeing is some sort of temporary error or a persistent one; and what is causing it.

peter · October 31, 2017, 3:41am

Can you post the dgraphzero logs as well? Any additional information you have would be useful.

jzhu077 · October 31, 2017, 3:54am

The dgraphzero looks pretty normal to me

I agree, the drgaphzero logs look normal.

What’s happening with the timestamps though? Are these the dgraphzero logs that correspond with the dgraph log? The timestamps don’t match.

jzhu077 · October 31, 2017, 4:07am

I only grab the last section of the very long logs. Oh I forgot to mention there are 10 dgraph instances in the cluster, and I’ve implemented the evenly distributed client-side routing.

2017/10/31 03:52:07in dgraphzero

I think they are matching

this is the dgraph log now

What would be really useful would be to see the dgraph and dgraphzero logs when the “connection is unavailable” and “predicate is being moved, please retry later” errors are received. When you do a mutation and receive either error, you should retry the mutation again later (for example, once every 10 seconds for the next 10 minutes). Seeing the what the logs look like when these events occur will help determine what’s going wrong (and if the problem is transient or persistent).

I assume the predicate is balanced since I use client-side balance control. e.g. create a client for each of the dgraph instance, and use them one after another to ingest. The predicates should be balanced after that. With this setup, would it be safe to turn off the rebalancing without sacrificing the query speed?

mrjn · October 31, 2017, 5:43am

Client doesn’t guarantee balanced data. It just round robins among the servers. The predicates could still be unbalanced because some predicates tend to be much heavier than others. So, the rebalancing act by zero is quite useful.

peter · October 31, 2017, 6:33am

When the “connection unavailable” and “predicate is being moved, please retry later” messages occur, can you provide the logs for the dgraphzeros, dgraphs, and your client? Also, can you confirm that the client retries? (should be visible in the client log). You’re using a custom client right? That’s what we need to sort out this issue.

jzhu077 · October 31, 2017, 8:24pm

Agreed, I should keep the rebalancing mechanism. Alternatively, is it easy to increase the time interval between rebalancing acts? i.e just increase some time setting. Because I would like to cut down the ingestion time down as much as possible. I know that it would be much faster to use bulk loading, but I would like to use the streaming ingestion as a short-term solution before I move to bulk loading, and I can also use this as a benchmark.

update:
I assume https://github.com/dgraph-io/dgraph/blob/master/cmd/dgraphzero/tablet.go#L55 this is the only place that I need to change to increase the rebalancing interval. Please confirm

jzhu077 · October 31, 2017, 8:36pm

RIght, retry logic is missing, however, this leads to an increase in ingestion time.

mrjn · October 31, 2017, 10:31pm

That’s the right place.
