Scalable blob storage integrated with scalable structured storage

A computer-implemented system utilizing a processor and memory for structured storage of one or more Binary Large Objects (Blobs) to be accessed by an application program being executed by a computing device, comprising:

• a primary structured storage index indexing the one or more Blobs in a structured storage system;
• a secondary hash index maintaining a compressed hash index of the primary structured storage, the secondary hash index facilitates efficient lookup of a Blob primary key, wherein the secondary hash index includes one or more hash values representing the one or more primary keys associated with the one or more Blobs;
• and
• a Blob store storing the one or more Blobs, wherein the Blob store comprises a Blob log stream having one or more uncommitted blocks and a Blob data stream having one or more committed blocks, wherein the primary structured storage index is indirectly mapped to the Blob data stream via the Blob log stream and the secondary hash index is directly mapped to the Blob data stream.

One or more computer storage media having a data structure embodied thereon for structured storage of one or more Binary Large Objects (Blobs) to be accessed by an application program being executed by a computing device, comprising:

• a primary structured storage index indexing the one or more Blobs in a structured storage system;
• a secondary hash index maintaining a compressed in-memory hash index of the primary structure storage index, the secondary hash index is an in-memory hash index that facilitates efficient lookup of a Blob primary key, wherein the secondary hash index includes one or more hash values representing the one or more primary keys associated with the one or more Blobs;
• a Blob store storing the one or more Blobs wherein the Blob store comprises a Blob log stream and a Blob data stream, wherein the Blob log stream processes single input/output operations in association with the primary structure storage index and the Blob data stream processes single in-memory lookups in association with the secondary hash index;
• and
• a table scheme that defines one or more data items included in the secondary hash index and a Blob header of the Blob data stream, wherein the one or more data items comprise Blob meta data that are retrieved when an associated Blob of the Blob meta data is accessed.
