=== CAT API changes
|
|
|
|
==== Use Accept header for specifying response media type
|
|
|
|
Previous versions of Elasticsearch accepted the Content-type header
|
|
field for controlling the media type of the response in the cat API.
|
|
This is in opposition to the HTTP spec which specifies the Accept
|
|
header field for this purpose. Elasticsearch now uses the Accept header
|
|
field and support for using the Content-Type header field for this
|
|
purpose has been removed.
|
|
|
|
==== Host field removed from the cat nodes API
|
|
|
|
The `host` field has been removed from the cat nodes API as its value
|
|
is always equal to the `ip` field. The `name` field is available in the
|
|
cat nodes API and should be used instead of the `host` field.
|
|
|
|
==== Changes to cat recovery API
|
|
|
|
The fields `bytes_recovered` and `files_recovered` have been added to
|
|
the cat recovery API. These fields, respectively, indicate the total
|
|
number of bytes and files that have been recovered.
|
|
|
|
The fields `total_files` and `total_bytes` have been renamed to
|
|
`files_total` and `bytes_total`, respectively.
|
|
|
|
Additionally, the field `translog` has been renamed to
|
|
`translog_ops_recovered`, the field `translog_total` to
|
|
`translog_ops` and the field `translog_percent` to
|
|
`translog_ops_percent`. The short aliases for these fields are `tor`,
|
|
`to`, and `top`, respectively.
|
|
|
|
==== Changes to cat nodes API
|
|
|
|
The cat nodes endpoint returns `m` for master eligible, `d` for data,
|
|
and `i` for ingest. A node with no explicit roles will be a coordinating
|
|
only node and marked with `-`. A node can have multiple roles. The
|
|
master column has been adapted to return only whether a node is the
|
|
current master (`*`) or not (`-`).
|
|
|
|
==== Changes to cat field data API
|
|
|
|
The cat field data endpoint adds a row per field instead of a column per field.
|
|
|
|
The `total` field has been removed from the field data API. Total field data usage per node
|
|
can be got by cat nodes API.
