To change the OpenStack Object Storage internal limits,
update the values in the
swift-constraints section in the
swift.conf file. Use caution when
you update these values because they affect the
performance in the entire cluster.
| Configuration option = Default value | Description |
|---|---|
account_listing_limit = 10000 |
The default (and maximum) number of items returned for an account listing request. |
container_listing_limit = 10000 |
The default (and maximum) number of items returned for a container listing request. |
max_account_name_length = 256 |
The maximum number of bytes in the utf8 encoding of an account name. |
max_container_name_length = 256 |
The maximum number of bytes in the utf8 encoding of a container name. |
max_file_size = 5368709122 |
The largest normal object that can be saved in the cluster. This is also the limit on the size of each segment of a large object when using the large object manifest support. This value is set in bytes. Setting it to lower than 1MiB will cause some tests to fail. It is STRONGLY recommended to leave this value at the default (5 * 2**30 + 2). |
max_header_size = 8192 |
The max number of bytes in the utf8 encoding of each header. Using 8192 as default because eventlet use 8192 as maximum size of header line. You may need to increase this value when using identity v3 API tokens including more than 7 catalog entries. See also include_service_catalog in proxy-server.conf-sample (documented in overview_auth.rst). |
max_meta_count = 90 |
The max number of metadata keys that can be stored on a single account, container, or object. |
max_meta_name_length = 128 |
The max number of bytes in the utf8 encoding of the name portion of a metadata header. |
max_meta_overall_size = 4096 |
The max number of bytes in the utf8 encoding of the metadata (keys + values). |
max_meta_value_length = 256 |
The max number of bytes in the utf8 encoding of a metadata value. |
max_object_name_length = 1024 |
The max number of bytes in the utf8 encoding of an object name. |
