Fine-grained Refresh Strategies for Managing Replication in Database Clusters
نویسندگان
چکیده
Relaxing replica freshness has been exploited in database clusters to optimize load balancing. In this paper, we propose to support both routing-dependant and routing-independent refresh strategies in a database cluster with multi-master lazy replication. First, we propose a model for capturing refresh strategies. Second, we describe the support of this model in a middleware architecture for freshnessaware routing in database clusters. Third, we describe an algorithm for computing refresh graphs, which are the core of all the refresh strategies.

Replica Refresh Strategies in a Database Cluster
Relaxing replica freshness has been exploited in database clusters to optimize load balancing. However, in most approaches, refreshment is typically coupled with other functions such as routing or scheduling, which make it hard to analyze the impact of the refresh strategy itself on performance. In this paper, we propose to support routing-independent refresh strategies in a database cluster wi...
متن کاملUsing Fuzzy Clustering for Advanced OODB Horizontal Fragmentation with Fine-Grained Replication
In this paper we present a new approach for horizontal object oriented database fragmentation combined with fine-grained object level replication in one step. We build our fragmentation/replication method using AI probabilistic clustering (fuzzy clustering). Fragmentation quality evaluation is provided using an evaluator function.
متن کاملThe Effect of Geopolymerization on the Unconfined Compressive Strength of Stabilized Fine-grained Soils
This study focuses on evaluating the unconfined compressive strength (UCS) of improved fine-grained soils. A large database of unconfined compressive strength of clayey soil specimens stabilized with fly ash and blast furnace slag based geopolymer were collected and analyzed. Subsequently, using adaptive neuro fuzzy inference system (ANFIS), a model has been developed to assess the UCS of stabi...
متن کاملScalable database replication through dynamic multiversioning
We scale the database back-end in dynamic content cluster servers by distributing read-only transactions on a set of lightweight database replicas while maintaining 1copy-serializability. This is contrary to conventional wisdom in replicated databases which says that one could have either 1-copy serializability or scalability, but not both. The key to scaling is a novel integrated fine-grained ...
متن کاملAdaptive Selective Replication for Complex Event Processing Systems
As of today, active replication is used in complex event processing systems to enable near zero latency take over in case of host failures. Moreover, elastic complex event processing systems adapt their resource consumption to the actual system load. However, active replication is a coarse-grained approach demanding the duplication of all used resources. Therefore, we envision a system adopting...
