Systems and methods for performing vulnerability assessment on partially functional applications
Systems and methods are described herein for performing vulnerability assessment on partially functional software applications (e.g., software applications currently at a phase in the development cycle prior to a user acceptance testing phase). By doing so, the system may detect vulnerabilities, if any, more easily based on the fewer functional components of the application. Additionally or alternatively, curing any vulnerabilities will require fewer modifications to the application's software, architecture, and/or intended functionality (as these characteristics are also earlier in their development cycle). |

Based on the analysis, the system marks which data tables and which columns of the data tables store personal data. The system receives a request to process personal data for a subject. From data tables that are marked as storing personal data, the system identifies records storing personal data for the subject. The system additionally identifies other data tables marked as storing personal data that reference or are referenced by the data tables including the records referencing the subject. The system processes the data stored in the columns that are marked as storing personal data. |

Moving window data deduplication in distributed storage
The present disclosure describes a service which provides primary in-line deduplication. A streaming application program interface (API) may allow for streaming records into a storage system with high throughput and low latency. As part of this process, the API allows user to add identifiers as a field used for data deduplication. The deduplication service keeps a moving window of the identifiers in memory and does in-line deduplication by quickly determining whether data is a duplicate. Keeping only deduplication keys in memory reduces the cost of running the service. Moreover, the real-time nature of the moving window approach allows for storing deduplication information alongside the data and accessing it immediately on read. In this regard, read after write consistency is supported, and costs are reduced. |

Automatic conversion of data models using data model annotations
Techniques and solutions are described for converting data models between formats, such as between a conceptual data model and a physical data model for a database system, or between a conceptual data model and artefacts to be implemented in the database system.

Synchronous replication for synchronous mirror copy guarantee
Techniques are provided for synchronous replication for synchronous mirror copy guarantee. A file system dependent technique for synchronous mirror copy guarantee is provided by overriding default behavior of a persistent fence so that the persistent fence is activated to block operations targeting a storage object having a synchronous replication relationship based upon the synchronous replication relationship being out of sync. The default behavior of the persistent fence is overridden to allow operations to be executed upon the storage object based upon the synchronous replication relationship being in sync. A file system independent technique for synchronous mirror copy guarantee is provided by intercepting operations before the operations are received by a file system. The operations are selectively forwarded to the file system or not based upon a state of a synchronous replication relationship. |

Quality score compression apparatus and method for improving downstream accuracy
This disclosure provides for a highly-efficient and scalable compression tool that compresses quality scores, preferably by capitalizing on sequence redundancy. In one embodiment, compression is achieved by smoothing a large fraction of quality score values based on k-mer neighborhood of their corresponding positions in read sequences. The approach exploits the intuition that any divergent base in a k-mer likely corresponds to either a single-nucleotide polymorphism (SNP) or sequencing error; thus, a preferred approach is to only preserve quality scores for probable variant locations and compress quality scores of concordant bases, preferably by resetting them to a default value. By viewing individual read datasets through the lens of k-mer frequencies in a corpus of reads, the approach herein ensures that compression “lossiness” does not affect accuracy in a deleterious way. |

Detecting changes in a namespace using namespace enumeration endpoint response payloads
Technologies for detecting changes in a namespace using namespace enumeration endpoint response payloads are disclosed. A namespace is enumerated at a first time by retrieving response payloads containing metadata describing each location in the namespace from a namespace enumeration endpoint. Signatures are generated based on the response payloads and stored. To determine if changes were made to the namespace between the first time and a subsequent second time, metadata is retrieved from the namespace enumeration endpoint for the namespace at the second time and signatures are generated. Signatures generated at the first time are then compared to the signatures generated at the second time. If the signatures are different, the items in the location in the namespace changed between the first time and the second time. Changes occurring in a location of the namespace can then be identified based on the metadata obtained at the first and second times. |

Upon a determination that the cumulative skew has reached the second threshold, the action is triggered. The action includes blocking the deletions of files having retention locks that have expired according to the system clock. |
