elasticsearchHow do I create an alias in Elasticsearch?
An alias in Elasticsearch is a reference to an index or a group of indices. It can be used to simplify complex queries, to switch out indices in a single operation, or to provide a single point of access to multiple indices.
Creating an alias in Elasticsearch is done using the PUT
command, as shown in the example below:
PUT /_aliases
{
"actions" : [
{ "add" : { "index" : "my_index_1", "alias" : "my_alias" } }
]
}
The output of this command will be {"acknowledged":true}
, indicating that the alias has been successfully created.
The PUT
command consists of two parts:
- The
actions
parameter, which is an array of objects defining what action should be taken. In this case, the action isadd
, which adds an index to the alias. - The
add
parameter, which is an object containing the index to add to the alias and the name of the alias.
For more information on creating and managing Elasticsearch aliases, please refer to the official documentation.
