`settings`::
|
|
(object) Settings to override from the leader index. Note that certain
|
|
settings can not be overrode (e.g., `index.number_of_shards`).
|
|
|
|
`max_read_request_operation_count`::
|
|
(integer) The maximum number of operations to pull per read from the remote
|
|
cluster.
|
|
|
|
`max_outstanding_read_requests`::
|
|
(long) The maximum number of outstanding reads requests from the remote
|
|
cluster.
|
|
|
|
`max_read_request_size`::
|
|
(<<byte-units,byte value>>) The maximum size in bytes of per read of a batch
|
|
of operations pulled from the remote cluster.
|
|
|
|
`max_write_request_operation_count`::
|
|
(integer) The maximum number of operations per bulk write request executed on
|
|
the follower.
|
|
|
|
`max_write_request_size`::
|
|
(<<byte-units,byte value>>) The maximum total bytes of operations per bulk write request
|
|
executed on the follower.
|
|
|
|
`max_outstanding_write_requests`::
|
|
(integer) The maximum number of outstanding write requests on the follower.
|
|
|
|
`max_write_buffer_count`::
|
|
(integer) The maximum number of operations that can be queued for writing.
|
|
When this limit is reached, reads from the remote cluster will be deferred
|
|
until the number of queued operations goes below the limit.
|
|
|
|
`max_write_buffer_size`::
|
|
(<<byte-units,byte value>>) The maximum total bytes of operations that can be
|
|
queued for
|
|
writing. When this limit is reached, reads from the remote cluster will be
|
|
deferred until the total bytes of queued operations goes below the limit.
|
|
|
|
`max_retry_delay`::
|
|
(<<time-units,time value>>) The maximum time to wait before retrying an
|
|
operation that failed exceptionally. An exponential backoff strategy is
|
|
employed when retrying.
|
|
|
|
`read_poll_timeout`::
|
|
(<<time-units,time value>>) The maximum time to wait for new operations on the
|
|
remote cluster when the follower index is synchronized with the leader index.
|
|
When the timeout has elapsed, the poll for operations will return to the
|
|
follower so that it can update some statistics. Then the follower will
|
|
immediately attempt to read from the leader again.
