Q1Domain Verified
In the context of Elasticsearch ILM, what is the primary purpose of a "rollover" action, and how does it contribute to efficient document lifecycle management?
To create a new index when certain conditions on the current index are met, transferring the alias to the new index.
To re-index documents from one index to another with updated mappings or settings.
To delete old indices that are no longer actively queried, thereby freeing up disk space.
To merge smaller indices into larger ones to improve search performance and reduce shard count.
Q2Domain Verified
When configuring an ILM policy, what is the role of "phases" and how do they enable progressive management of document lifecycles?
Phases are used to segment data within an index based on its content for faster querying.
Phases define the specific Elasticsearch cluster nodes where indices will be stored and managed.
Phases dictate the network protocols used for inter-node communication within an Elasticsearch cluster.
Phases represent distinct stages in an index's lifecycle, each with its own set of actions and conditions.
Q3Domain Verified
Consider an ILM policy where the "Warm" phase has a "shrink" action configured with `number_of_shards: 1`. What is the most significant benefit of this configuration for an index that has transitioned into the Warm phase?
It allows for faster data ingestion by creating more, smaller shards.
It significantly improves search latency by distributing query load across fewer, larger shards.
It reduces the overall disk space occupied by the index by compressing data more efficiently.
It optimizes the index for archival and long-term storage by reducing the number of primary shards.
