Elasticsearch runs an automatic process called rebalancing which moves shards between the nodes in your cluster to improve its balance. Rebalancing obeys all other shard allocation rules such as allocation filtering and forced awareness which may prevent it from completely balancing the cluster.
Mar 21, 2017 · if using spinning disk, you can add to the elasticsearch.yml to increase the indexing speed: index.merge.scheduler.max_thread_count: 1 (see here) Update before recovery your index settings with: "refresh_interval" : "-1" and put it back at its default value afterward (see the doc) If you don't care about searching yet, the following on your ES5 ...
There are two basic processes which govern how shards are distributed among the Elasticsearch nodes: Shard allocation, which is an algorithm by which Elasticsearch decides which unallocated shards should go on which nodes, Shard rebalancing, which is the process of moving a shard from one node to another. Shard allocation explained
29.01.2019 · Speed up shard allocation on Elasticsearch 6.x single node cluster Thomas_Ardal (Thomas Ardal) January 29, 2019, 1:07pm #1 I'm currently upgrading a "cluster" (with a single node) from Elasticsearch 1.x to 6.x. Everything is working out great, but I experience very slow shard allocation on 6.x.
Cluster shard allocation This refers to the process by which any shard including new, recovered or rebalanced shards are allocated to Elasticsearch nodes. Cluster shard allocation may be temporarily disabled during maintenance in order to avoid shards from being relocated to nodes that are being restarted and may temporarily leave the cluster.
The Elasticsearch Check-Up is free and requires no installation. Overview Cluster shard rebalancing and allocation are often confused with each other. Cluster shard allocation This refers to the process by which any shard including new, recovered or rebalanced shards are allocated to Elasticsearch nodes.

Jan 02, 2022 · This setting will only allow allocation for primary shards. Make sure to set this to null after the node comes back online, otherwise you will have unassigned replicas. Synced Flush You can perform a synced flush just before restarting the node. Elasticsearch tries to ensure that replicas have all the same data as primaries.
