Abstract: Providing messages for Java message service (JMS) is disclosed. A described method includes determining timestamp information associated with a first Java™ message service (JMS) message. The timestamp information represents a time when the JMS message is either generated or received by a processing device. The method also includes determining destination information associated with the JMS message. The method further includes converting the JMS message into a first key-value data pair having a key data and a value data. The key data includes the timestamp information and the value data includes the destination information of the first JMS message.

Abstract: A processing device translates a set of federated queries submitted to a federated data source server into a set of native data source queries for the particular type of data source using a federated data source connector for a particular type of data source, inputs the set of native data source queries for the particular type of data source into a component corresponding to the particular type of data source, marks the component in view of the set of native data source queries, and generates output indicating whether one or more of the set of native data source queries is not acceptable as input for the component. The marked component and the output indicate whether the federated data source connector for the particular type of data source includes an error.

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.

Abstract: An example method of submitting a federated query to one or more data sources belonging to a federation includes splitting a zone into a plurality of zone subsets. The zone includes a plurality of data sources belonging to a federation. The plurality of zone subsets has disjoint sets of data sources belonging to the federation. The method also includes receiving a federated query from a client. The federated query includes a plurality of source queries. Each source query of the plurality of source queries is specific to an autonomous data source belonging to the federation. The method further includes determining the client's assigned zone subset of the plurality of zone subsets. The method also includes submitting the federated query to the client's assigned zone subset. The plurality of source queries is submitted to one or more data sources in the zone subset to which the client is assigned.

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 batch query processing includes accumulating data queries in a query holding area of a query assistant running in a computer server, separating the accumulated data queries into a plurality of partitions, ordering the partitions, ordering the accumulated data queries within each of the partitions, and processing the accumulated data queries in an order based on the ordering of the partitions and the ordering of the data queries within each of the partitions. Each of the partitions includes data queries with a respective from-type. Each respective from-type is associated with a combination of storage tables accessed by each of the data queries in a corresponding partition. In some examples, ordering the accumulated data queries within each of the partitions includes processing the data queries in each partition against a test data set and ordering the data queries based on results of the processing.
