Absolute limits control the total number of specific objects that a user can have or process in Cloud Files. Absolute limits are fixed.
The following table lists the absolute limits in Cloud Files.
|Containers per account||Maximum number of containers per account||500,000 containers|
|Container listing||Maximum number of containers that can be listed at one time||10,000 containers|
|Pseudo hierarchical folders and directories||Simulated hierarchical structure
within a single container,
created by adding a forward
|Account, container, and object metadata limits||Maximum metadata limits||90 distinct metadata items at the most. Each piece of metadata can have a 128-character name length with a 256 maximum value length. The total length of all names and values cannot exceed 4096 bytes.|
|Number of object segments per static large object (SLO)||Maximum number of object segments per SLO||1,000 object segments|
|TTL for a CDN-enabled container||Maximum TTL for a CDN-enabled container||1 year (31,536,000 seconds)|
|Container name length||Maximum length of container name||256 bytes|
|Object name length||Maximum length of object name||1024 bytes|
|Upload limit for a request||Maximum object size for an upload in a single request||5 GB (For larger files, create a manifest file.)|
|CDN file size limit||Maximum size of file that can be served from CDN||10 GB|
|Rate limit for write operations||Maximum number of write operations per second per container, where a write operation is a COPY, DELETE, POST, or PUT. If you reach this rate limit, Cloud Files slows the processing of write requests for the container to 100 write operations per second per container.||100 write operations per second per container|
