### Description

I get the following error message running a batch job to load records into my Weaviate nodes.

```auto
Reason: local index "<INDEX_NAME>" not found: deadline exceeded for waiting for update: version got=0 want=64

```

After doing some digging I found this on my node:

```auto
{"got":0,"level":"debug","msg":"wait for update version","time":"2024-07-22T21:49:57Z","want":64}

```

Any ideas what could be causing this?

- Weaviate Server Version: 1.25.8
- Deployment Method: Docker on AWS ECS using Fargate
- Multi Node? Number of Running Nodes: 2
- Client Language and Version: Python 4.6.5

Oh, had to increase my timeout time for this. Here’s the config I ended up using:

```auto
weaviate.config.AdditionalConfig(
            timeout=weaviate.config.Timeout(init=30, query=60, insert=120)
        )

```

Hi!

Can you share the docker compose you have used?

Also, for multi node, it is best to have at least 3 nodes. 🤔

I’m using Services and Task Definitions on AWS ECS so it’s a bit tricky to mimic a Docker compose. I’ll increase the nodes to 3 based on recommendation, but what is the benefit of doing that?

Hi!

It should show on logs, but if not properly configured, it may have a hard time defining the leader in the cluster:

> **[Cluster Architecture | Weaviate - Vector Database](https://weaviate.io/developers/weaviate/concepts/replication-architecture/cluster-architecture)**
>
> This page describes how the nodes or clusters in Weaviate's replication design behave.

However, not sure it would produce the symptoms you had, but wouldn’t work at all.

Perfect, I’ll dig in and read.
