Abstract: In an approach to improve asynchronous replication in database clusters embodiments retain committed transactions during database cluster replication. Embodiments build and run asynchronous replication logic using database nodes running as one or more standalone nodes, wherein the asynchronous replication logic is responsible for data replication from a primary database node to one or more secondary database nodes. Embodiments register a replication reader to a sender node to replicate journal logs and replay the journal logs on the one or more secondary database nodes. Further, embodiments monitor replication lag metrics from the sender node and notify a replication source and a replication target of a generated replication plan, wherein the cluster controller instructs the replication source and the replication target to be ready to initiate the replication plan. Additionally, embodiments adjust a replication plan to allow the asynchronous replication logic to catch up and complete uncommitted transactions.

Abstract: A method and system for improving throughput of a fluidic system such as a biopolymer analysis system by cleaning accumulated or clogging biopolymer from the fluidic system is disclosed. The method and system utilize a light energy source to photocleave the biopolymer molecules that may accumulate or aggregate in the fluidic system or clog a passageway. The accumulated biopolymer may be exposed to a light energy source for a sufficient period of time such that the biopolymer molecule is dosed with sufficient energy to photocleave the biopolymer molecules, thereby restoring the efficiency of and flow through the system.
