摘要： A system and method for implementing a database system is presented. A database cluster can comprise multiple database servers. Each database server is configured to regularly compile various statistics upon the occurrence of a triggering event. These statistics can be stored along with the statistics of each database server in the cluster of database servers. Upon the occurrence of various conditions, corrective actions can be implemented. The conditions can include the inability to achieve performance thresholds. The conditions also can include not meeting the performance of other database servers in the cluster. The corrective action can include removing a server temporarily from the cluster or rebooting the server. In addition, a database server can cause the corrective action on other database servers in the cluster. Other embodiments also are disclosed.

摘要： A system and method for implementing a database system is presented. A database system comprises a load balancer and a database partitioned into a first and second shard. Coupled to the load balancer are a first plurality of database servers and a second plurality of database servers. Each of the first plurality of database servers contains a copy of the first shard of the database. Each of the second plurality of database servers contains a copy of the second shard of the database. Queries are sent to a database server in the first plurality of database servers based on a suitability score of the database server determined by characteristics of each server and a current status of each server, where the query is sent to the server in the first plurality with the highest suitability score. Other embodiments also are disclosed.

摘要： Various embodiments include a system for grouping a set of distinct records in a database system, the database system comprising a first database cluster H and a second database cluster L. In many embodiments, the system can comprise one or more processing modules and one or more non-transitory memory storage modules storing computing instructions configured to run on the one or more processing modules. In some embodiments, the computer instructions can be configured to perform acts of determining, for each distinct record (i) of the set of distinct records, whether the record is a first priority or a second priority; for each distinct record (i) of the set of distinct records which is determined to be the first priority, storing the record in the first database cluster H, wherein the first database cluster H comprises a first computer server; and for each record (i) of the set of distinct records which is determined to be the second priority, storing the record in the second database cluster L. In these embodiments, the second database cluster L can comprise a second computer server different from the first computer server, and the first computer server can have greater processing power than the second computer server. In some embodiments, the first priority can be a higher priority than the second priority. Other embodiments are also disclosed herein.

摘要： A system and method for using past information for future search results is disclosed. A database system may comprise a first database cluster H and a second database cluster L. Social media mentions are mapped to products in the database system. Thereafter, each record in the database system is tracked to determine if mentions on social media platforms are increasing or decreasing, using a social media popularity trend signal. The social media popularity trend signal is created by comparing social media mentions during one time period to social media mentions in another time period. Other embodiments are also disclosed herein.

摘要： A system for dynamically varying traffic routing modes in a distributed database system is presented. A database system comprises a load balancer and a database partitioned into a first and second shard. Coupled to the load balancer are a first plurality of database servers and a second plurality of database servers. Each of the first plurality of database servers contains a copy of the first shard of the database. Each of the second plurality of database servers contains a copy of the second shard of the database. Each server in the first plurality of database servers sends queries to a server in the second plurality of database servers using a round-robin system in which servers in the second plurality of database servers take turns processing incoming queries, as a method of distributing load among the multiple servers. Other embodiments also are disclosed.

摘要： A system and method for maintaining consistency across a decentralized database cluster is presented. A database cluster can contain a plurality of database servers, each hosting a copy of the same database. In a system without a centralized coordinating server, a message queue can be used to simultaneously provide updates to each database server in the database cluster. A When a database server receives an index update message, it adds message to a queue indicating it has received the message and watches an index update node. Once every server in the cluster has added a message to the queue, it is known that every database server has received the message. The update can be performed for each server and the changes committed simultaneously. In such a manner, all database servers in the cluster perform an update at approximately the same time. Other embodiments also are disclosed.

摘要： A system and method for predicting search term popularity is disclosed herein. A database system may comprise a first database cluster H and a second database cluster L. A machine learning algorithm is trained to create a predictive model. Thereafter, for each record in a database system, the predictive model is used to calculate a probability of the record being accessed. If the calculated probability of the record being accessed is greater than a threshold value, then the record in the first database cluster H; otherwise, the record is placed in the second database cluster L. Training the machine learning algorithm comprises inputting a training feature vector associated with the record into the machine learning algorithm, inputting a cost vector into the machine learning algorithm, and iteratively operating the machine learning algorithm on each record in the set of records to create a predictive model. Other embodiments are also disclosed herein.
