Common Mistakes

Using 'warm' or 'cold' instead of 'hot' for hot nodes.

The hot node attribute is set as "hot" to identify nodes that handle indexing and searching.

💡 Hint

Common Mistakes

Confusing 'warm' with 'hot' or 'cold' phases.

The lifecycle phase 'warm' is used for indices that are less frequently accessed but still searchable.

💡 Hint

Common Mistakes

Using 'archive' or 'warm' instead of 'cold' for cold nodes.

Cold nodes should have the attribute set to 'cold' to properly identify their role in the cluster.

💡 Hint

Common Mistakes

Mixing 'warm' or 'cold' values in hot phase settings.

For the hot phase, both the lifecycle phase and node attribute should be set to 'hot'.

5fill in blank

hard

Fill all three blanks to define a cold node with the correct lifecycle phase and node attribute.

Elasticsearch

"index.lifecycle.phase": "[1]",
"node.attr.box_type": "[2]",
"index.routing.allocation.require.box_type": "[3]"

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using different values for lifecycle phase and node attributes causing misallocation.

Cold nodes and indices use 'cold' for lifecycle phase, node attribute, and routing allocation to ensure data is stored on cold nodes.
