Stretchy is an elasticsearch manager. It's main feature is zero-down-time remapping of data.

Currently under development

• Elasticsearch 6.x
• Elasticsearch 7.x

• Zero-down time remapping of an index (including data-transfer)
• Initialize indices based on config files
• Show and compare mapping configurations

For stretchy to work, your configuration needs to be defined in JSON or YAML format. Each file should contain a valid structure for index creation (https://www.elastic.co/guide/en/elasticsearch/reference/master/indices-create-index.html). The name of the file will be used as the base alias name.

stretchy apply --elasticsearch-host=http://localhost:9200 \
    --index-prefix=stretchy \ # A prefix that will be applied on each index and alias
    --path=./configs \ # Path where to search for configurations file
    --format=yaml \ # Format of the configurations file
    --enable-soft-update \ # Allows inplace remapping
    --dry-run # Do not apply changes

Some examples can be found here

• Refactor configuration package
• Create a configuration file based on an existing index
• Add metadata on indexes created with stretchy and keep only X old index versions (should be configurable)
• Move utils out from this project
• Enrich documentation and examples
• Create a new repo for homebrew's release
