elasticsearchHow do I create an index in Elasticsearch?
To create an index in Elasticsearch, you can use the PUT
API endpoint. The syntax for creating an index is as follows:
PUT /<index_name>
For example, to create an index called my_index
, the following command can be used:
PUT /my_index
The response to the above command will look like the following:
{
"acknowledged": true,
"shards_acknowledged": true,
"index": "my_index"
}
You can also specify the number of shards and replicas while creating an index. The syntax for doing so is as follows:
PUT /<index_name>
{
"settings" : {
"number_of_shards" : <number_of_shards>,
"number_of_replicas" : <number_of_replicas>
}
}
For example, to create an index called my_index
with 5 shards and 3 replicas, the following command can be used:
PUT /my_index
{
"settings" : {
"number_of_shards" : 5,
"number_of_replicas" : 3
}
}
The response to the above command will look like the following:
{
"acknowledged": true,
"shards_acknowledged": true,
"index": "my_index"
}
Parts of the code:
PUT
: The API endpoint used to create an index.<index_name>
: The name of the index to be created.number_of_shards
: The number of shards to be created with the index.number_of_replicas
: The number of replicas to be created with the index.
