Index Management

Index Management​

The Index Management features allow you to create, configure, and maintain Elasticsearch indices.

Index Operations​

Create Index​

Create new indices with custom settings:

  • Index Name: Set the index identifier
  • Shards: Configure primary shard count
  • Replicas: Set replica configuration
  • Settings: Custom index settings (refresh interval, merge settings, etc.)
  • Mappings: Define field mappings and types

Modify Index​

Change existing index configuration:

  • Index Settings: Modify refresh intervals, merge policies, and other settings
  • Aliases: Add or remove index aliases
  • Mappings: Update field mappings (with compatibility checking)

Delete Index​

Remove indices from the cluster. Requires confirmation to prevent accidental deletion.

Index Information Tabs​

When viewing an index, you can access several tabs:

Settings Tab​

View and edit index settings:

  • Number of shards and replicas
  • Refresh interval
  • Merge policies
  • Analysis settings
  • Other index configuration

Mappings Tab​

View field mappings and types:

  • Field names and data types
  • Field properties and analyzers
  • Nested fields and objects
  • Dynamic mapping settings

Statistics Tab​

View index metrics:

  • Document count
  • Index size
  • Segment count
  • Merge activity

Best Practices​

  • Always create indices with appropriate replication for high availability
  • Use aliases for zero-downtime index updates
  • Monitor index size and segment count regularly
  • Archive or delete old indices to manage cluster size
