Max Objects * | Minimum ES Nodes | Shards | Notes |
|---|---|---|---|
200M | 1 | 5 | Must set shard replicas to zero. (see below) Do not use it without a robust ES backup strategy. |
600M | 3 | 5 | This was the default shard count before Swarm 16. |
1000M | 5 | 10 | Swarm 16 increases the default shard count to Swarm 1610. |
1600M | 8 | 15 | |
2000M | 10 | 20 |
* Some workloads like Veeam Backup produce a high listing load which requires more elasticsearch nodes, up to one node per shard. Veeam also produces a high object delete and retention period update load, resulting in deleted documents being almost half of the elasticsearch index. Deleted documents are gradually “merged” out of the index, but they have the same impact on listing performance and sizing requirements as much as live documents.
