Get global checkpoints API
The purpose of the get global checkpoints api is to return the current global checkpoints for an index. This API allows users to know the what sequence numbers have been safely persisted in Elasticsearch.
Polling on global checkpoint advance
The API has an optional polling mode enabled by the wait_for_advance query parameter. In polling mode, the API will only return after the global checkpoints advance past the provided checkpoints. By default, checkpoints is an empty array, which will lead to the API returning immediately.
If a timeout occurs before the global checkpoints advance past the provided checkpoints, Elasticsearch will return the current global checkpoints and a boolean indicating that the request timed out.
Currently the wait_for_advance parameter is only supported for one shard indices.
Polling on index ready
By default in polling mode, an exception will be returned if the index does not exist or all the primary shards are not active. In polling mode, the wait_for_index parameter can be used to modify this behavior. If wait_for_index is set to true, the API will wait for the index to be created and all primary shards to be active.
If a timeout occurs before these conditions are met, the relevant exception will be returned.
Currently the wait_for_index parameter is only supported when wait_for_advance is true.
Request
GET /<index>/_fleet/global_checkpoints
Path parameters
<index>
(Required, string) A single index or index alias that resolves to a single index.
Query parameters
wait_for_advance
(Optional, Boolean) A boolean value which controls whether to wait (until the timeout) for the global checkpoints to advance past the provided checkpoints. Defaults to false.
wait_for_index
(Optional, Boolean) A boolean value which controls whether to wait (until the timeout) for the target index to exist and all primary shards be active. Can only be true when wait_for_advance is true. Defaults to false.
checkpoints
(Optional, list) A comma separated list of previous global checkpoints. When used in combination with wait_for_advance, the API will only return once the global checkpoints advances past the checkpoints. Defaults to an empty list which will cause Elasticsearch to immediately return the current global checkpoints.
timeout
(Optional, time units) Period to wait for a global checkpoints to advance past checkpoints. Defaults to 30s.
Response body
global_checkpoints
(array of integers) The global checkpoints for the index.
timed_out
(Boolean) If false the global checkpoints did not advance past the checkpoints within the specified timeout.
