The embodiments disclosed herein are related to a computing system for generating a mask-augmented inverted index. The mask-augmented inverted index is structured to allow phrase query searching while minimizing the amount of computing system processing and memory resources needed to generate the mask-augmented inverted index. In one embodiment, a first token is mapped to a first listing of documents that include the first token. A first mask is included that comprises a probabilistic representation of a set of integers corresponding to one or more locations of the first token in each of the individual documents of the first listing. A second mask is included that comprises a probabilistic representation of a set of integers that indicate a positional relationship between the first token and one or more other tokens in each of the individual documents of the first listing.

Mask-augmented inverted index

In various implementations, specific attributes found in images can be used in a visual-based search. Utilizing machine learning, deep neural networks, and other computer vision techniques, attributes of images, such as color, composition, font, style, and texture can be extracted from a given image. A user can then select a specific attribute from a sample image the user is searching for and the search can be refined to focus on that specific attribute from the sample image. In some embodiments, the search includes specific attributes from more than one image.

Searching using specific attributes found in images

In various implementations, one or more specific attributes found in an image can be modified utilizing one or more specific attributes found in another image. Machine learning, deep neural networks, and other computer vision techniques can be utilized to extract attributes of images, such as color, composition, font, style, and texture from one or more images. A user may modify at least one of these attributes in a first image based on the attribute(s) of another image and initiate a visual-based search using the modified image.

Modifying at least one attribute of an image with at least one attribute extracted from another image

A system for maintaining a repository replication system includes an interface and a processor. The interface is to receive a request to modify a repository, wherein the repository comprises repository copies. The processor is to determine whether modifying the repository resulted in an indication of an error, wherein the indication of the error is based at least in part on a plurality of checksums, wherein a checksum of the plurality of checksums is associated with a repository copy of the repository copies; and in the event that modifying the repository resulted in the indication of the error: queue a repair request to repair the error; and execute a repair process to repair the error associated with the repair request, wherein executing the repair process occurs asynchronously to queuing the error request.

Decoupled maintenance and repository synchronization error detection

A system for directing reads includes an input interface and a processor. The input interface is to receive a request to read from a plurality of servers. The processor is to determine a set of weights for a set of healthy servers of the plurality of servers and determine a server to receive the request based at least in part on the set of weights.

Using read weight affinities to optimize the reading of block cache data

Provided are methods and computer program products for monitoring the contents of network traffic in a network device and performing correlation analysis of collected performance metrics to help identify reasons for network performance issues. Methods for correlation analysis include selecting scope and network metric types to include in the correlation analysis to generate an educated candidate set for correlation analysis. The correlation analysis methods result in a hypothesis set that assist the operator in identifying transactions and infrastructure problems resulting in network performance degradation.

A system for command handling for replicated repositories includes an input interface and a processor. The input interface is to receive a command. The processor is to determine a set of servers to receive the command, determine whether responses match for the command for each server of the set of server, and in the event the responses do not match, determine whether the responses are required to match for the command and in the event the responses are not required to match for the command, determine a unified response.

Remote procedure calls in a replicated server system

A system for a distributed repository includes an input interface and a processor. The input interface is to receive a request to change a portion of code. The processor is to determine a change reference and an existing reference, indicate to lock one or more repositories, determine whether swapping references is approved by a vote, and in the event that swapping references is approved by a vote, swap the references and indicate to unlock the one or more repositories.

Distributed code repository with limited synchronization locking

Provided are methods and computer program products for analyzing and tracing the contents of network traffic in a network device and to help identify network performance issues. Methods for analyzing traffic include identifying thread identifiers associated with transactions, determining related events, and associating similar transactions and events into an aggregated list of transactions. Methods of tracing transactions include identifying thread identifiers associated with transactions and related events and serializing events into a serialized list of events to facilitate tracing single transactions.

Methods and computer program products for transaction analysis of network traffic in a network device

Provided are methods and computer program products for analyzing transactions across a network and to help identify network performance issues. Methods for analyzing traffic include identifying an outbound transaction and a related transaction type, and identifying candidate inbound transactions that have the same transaction type as the transaction type of the outbound transaction. One or more transaction data parameters may be selected that correspond to the outbound or inbound transactions. Candidate transactions may be determined to be related to the outbound transaction based on one or more transaction data parameters.
