Abstract: Data storage management is carried out by an Internet of Things platform having access to operational and long-term databases carrying tables for storing device-related data emitted from connected devices. Device-related data is received and stored in operational database table entries. Tables are associated with devices. Table entries are associated with entry dates. A table in the operational database is monitored to obtain load statistics. Data from the operational database is offloaded by replication to the long-term database. Queries against operational database tables are tracked to obtain query statistics. Cleanup rules determining timeframes within which data stored in operational database table entries are to be deleted are set up, based on a date of data entry. Cleanup rules currently set up are carried out as a retention run, based on the load statistics and/or query statistics.

Abstract: The present technology concerns a complex event processing (CEP) engine for processing CEP queries over data streams. The CEP engine has a parser, adapted for parsing a received CEP query into a logical query graph and a translator adapted for translating the logical query graph into a physical query plan in accordance with one of a plurality of data stream representations. The logical query graph is independent of the plurality of data stream representations.

Abstract: Certain example embodiments relate to techniques for investigating event streams in complex event processing (CEP) environments. Input events from one or more input event streams and query registration-related events from a registration event stream are received. Query registration-related events are associated with actions taken with respect to queries performed on the input event stream(s). Event-based profiles are developed by subjecting the received input events to a profiling CEP engine. Event-based profiles include data mining related and/or statistical characteristics for each input event stream. Query-based profiles are developed by subjecting the received query registration-related events to the CEP engine. Query-based profiles include data indicative of how relevant the queries performed on the input event stream(s) are and/or how those queries are relevant to the input event stream(s) on which they are performed.
