Abstract
Provided are techniques for optimized content object storage service for large scale content. A content object file is created. An index entry for the content object file is created with a content object key and a content object location. The content object file is appended to an aggregated file on a storage node. In response to a request to retrieve the content object file from the aggregated file, the content object key is used to access the content object location that describes the storage node, a name of the aggregated file, an offset into the aggregated file, and a size of the content object file to retrieve the content object file.
Claims18
A computer-implemented method, comprising operations for:
- creating an aggregated file that includes a plurality of content object files, wherein a content object file of the plurality of content object files in the aggregated file has a plurality of versions;
- creating an indexing structure with an entry for each content object file of the plurality of content object files in the aggregated file, wherein each entry comprises a location of that content object file in the aggregated file, a content object name, a content object key, and a content object version number;
- receiving a request to update an existing content object file of the plurality of content object files in the aggregated file with an updated content object file;
- determining whether versioning is enabled;
- in response to determining that versioning is enabled,
- creating a new index entry in the indexing structure for the updated content object file with a different location, a same content object name as the existing content object file, a different content object key, and a content object version number that is incremented by one based on a last content object version number of the existing content object file;
- in response to determining that the versioning is not enabled,
- setting a delete flag to indicate that the existing content object file is to be deleted;
- removing an existing index entry from the indexing structure for the existing content object file;
- and
- creating a new index entry in the indexing structure for the updated content object file with a content object version number of one;
- and
- dynamically appending the updated content object file to the aggregated file sequentially.

- in response to determining that the versioning is not enabled,
- setting a delete flag to indicate that the existing content object file is to be deleted;
- removing an existing index entry from the indexing structure for the existing content object file;
- and
- creating a new index entry in the indexing structure for the updated content object file with a content object version number of one;
- and
- dynamically appending the updated content object file to the aggregated file sequentially.
