refresh()¶

    $response = $e->indices->refresh(
        index => 'index' | \@indices    # optional

flush()¶

    $response = $e->indices->flush(
        index => 'index' | \@indices    # optional
    );

The flush() method causes the specified indices (or all indices) to be written to disk with an "fsync", and clears out the transaction log. This process normally happens automatically.

Query string parameters:
"allow_no_indices",
"error_trace",
"expand_wildcards",
"force",
"human",
"ignore_unavailable",

See the flush index docs <http://www.elastic.co/guide/en/elasticsearch/reference/current/indices-flush.html> for more information.

flush_synced()¶

    $respnse = $e->indices->flush_synced(
        index => 'index' | \@indices    # optional
    );

The flush_synced() method does a synchronised flush() on the primaries and replicas of all the specified indices. In other words, after flushing it tries to write a "sync_id" on the primaries and replicas to mark them as containing the same documents. During recovery, if a replica has the same "sync_id" as the primary, then it doesn't need to check whether the segment files on primary and replica are the same, and it can move on directly to just replaying the translog. This can greatly speed up recovery.

Synced flushes happens automatically in the background on indices that have not received any writes for a while, but the flush_synced() method can be used to trigger this process manually, eg before shutting down. Any new commits immediately break the sync.

See the flush synced docs <http://www.elastic.co/guide/en/elasticsearch/reference/current/indices-synced-flush.html> for more information.

"allow_no_indices",
"error_trace",
"expand_wildcards",
"flush",
"human",
"ignore_unavailable",
