A first virtual cube having three orthogonal vanishing points with a random 3D orientation is superimposed on to the image. The line segments of the image are classified grouped into 3D-directional groups. A second virtual cube is superimposed on to the image with an initial 3D orientation. An optimal 3D orientation of the second virtual cube is computed by iteratively changing the 3D orientation of the second virtual cube and measuring perpendicular distances of the three orthogonal vanishing points to the three line segment groups in each iteration starting with the initial 3D orientation, wherein the optimal 3D orientation of the second virtual cube being one that provides shortest perpendicular distances. Co-variances of the orthogonal vanishing points of the second virtual cube at the optimal orientation are computed. Ground orientation is computed from the second virtual cube at the optimal orientation.

A mechanism that dynamically creates a new access policy for a set of database servers when a policy violation has been identified in a database access response issued by any database in the set. The new access policy is then propagated in real-time and instantiated across the set of database servers so as to inoculate the other database servers and pre-empt any new compromise of information based on the intruder's actions that were found to have produced the policy violation in the first instance. Thus, the approach uses a response policy violation at one database server of a set to trigger generation of a new request access policy that is then instantiated across one or more other database servers. This response policy violation-to-request access policy instantiation occurs in substantially real-time so that the intruder cannot use a prior successful access request to obtain information from other databases using a similar strategy.

Techniques for handling highly amortized metadata page updates in storage clusters with delta log-based architectures. In response to performance of a transaction commit operation, bulk metadata pages are written in a transactional area of persistent memory in association with a unique transaction identifier. Further, raw delta updates to metadata pages and, for each bulk metadata page, a specialized flag, are written to a metadata delta log in association with the unique transaction ID. The specialized flag provides an indication that all delta updates that have occurred previous to the writing of a bulk metadata page are no longer relevant and should be dropped. The raw delta updates to metadata pages and specialized flags are updated in a volatile memory structure. The bulk metadata pages are flushed from the transactional buffer area directly to a metadata store of a storage array in a manner that bypasses the metadata delta log.

Data convolution for geographically diverse storage is disclosed, wherein the data convolution is based on a valency metric, determination, parameter, etc. Valency can be correlated to a data object and can be inherited by a chunk comprising the data object. Valency can indicate permitted levels of convolution for a chunk. A chunk resulting from convolving at least two other contributing/participating chunks can be determined to have a valency that can be less than either of the two contributing/participating chunks. A chunk with a zero valence can be restricted from contributing to a convolution. Where the at least two other chunks both have infinite valency, the resulting convolved chunk can also have infinite valency. A chunk resulting from convolving participating chunks having mixed valency values can be reconvolved. Valency can enable orchestrating convolution of chunks, for example, to conserving storage space, mitigate computing resource consumption, etc.

The described technology is generally directed towards a streaming data storage system that compacts older stream data by aggregating that data based on an aggregation function, and replacing the older data with the aggregated data. The technology works with a data stream in different storage tiers (e.g., Tier-1 and Tier-2), provides consistent data stream compaction of data streams having multiple segments, works with different reader applications at different event positons in the data stream, and allows the use of multiple, different aggregation functions. The technology facilitates more efficient compaction for a data stream with a lesser number of routing keys by maintaining per-chunk aggregated data for such data streams.
