Abstract: An example method for routing a message in a dynamic service mesh includes receiving at a mesh point a first message from a sender service and determining, based on a routing table, whether the mesh point has previously received a second message from the sender service. When the mesh point is determined to not have received the second message from the sender service, the first message is routed to a target service in the dynamic service mesh. The method includes receiving an indication of whether the first message has been accepted by the target service and updating the routing table based on the indication. When the indication indicates that the first message has been rejected by the target service, the first message is routed from the mesh point to a second target service.

Abstract: A system and method of dynamic collaboration during query processing includes determining a load factor for a data source, receiving a query at a query assistant running on a computer server, determining a complexity of the query, adjusting the complexity by the load factor, simplifying the query by removing one or more first query elements from the query when the adjusted complexity is above a threshold, forming a query plan where the first query elements are designated for processing outside the data source, and performing the query plan by sending one or more abbreviated queries to the data source and processing the first query elements using the query assistant. The abbreviated queries are based on the query with the first query elements removed. In some examples, the query may be iteratively simplified until a second adjusted complexity of a simplified version of the query falls below the threshold.

Abstract: A system and method of querying hybrid multi data sources includes receiving a query at a hybrid multi data source running on a computer server, creating a list of data sources, filtering the list of data sources based on data source hints included in the query, filtering the list of data sources based on data source rules, forming one or more query plans for processing the query, evaluating each of the query plans, selecting a first query plan from the query plans based on results of the evaluating, and performing the first query plan. Each query plan corresponds to a data source in the filtered list of data sources. In some examples, the first query plan has a lowest cost of each of the query plans. In some examples, the first query plan is based on probabilities associated with the cost of each of the query plans.
