![]() ![]() The test program is another one of SAWS'' efforts to balance the cost of conservation with the cost of new water resources. But we want it to be a reasonable amount." "We see that people value a product more if they are paying some amount for it. "People should have some skin in the game," Hayden said. But it won't be as much of a discount as the test group received. If SAWS decides to move forward and discount the devices to its half million customers, coupons will be made available, although that price has not been set. The test program runs through the summer when water usage spikes. if there is a big difference, we'll certainly consider it more likely," Hayden said. if there is not much of a difference between those two groups, we probably won't do a long term program with it. "The way we fund programs at SAWS is based on how much water is saved. SAWS is watching to see if the test group uses less water than non-Flume customers. A smart phone mobile app lets users view water usage as it happens. It provides real-time data via a bridge that connects to a user's home Wi-Fi. "Studies have shown that the more information people have on their actual water use, the less water they use," Hayden said.įlume works this way: A water sensor attaches to the water meter. But those in SAWS' pilot program paid just $30. "The reason why this is of interest to SAWS is a) we're trying to educate our customers about water use and b) it's relatively inexpensive," said Anne Hayden, the company's communications manager. That could change if a San Antonio Water System test program becomes the norm.įive hundred San Antonians are experimenting with Flume, a device that not only provides water usage consumption 24/7 to their smart phones but also lets them know if there is a leak in their system. Using Flume, we can get the data from multiple servers immediately into Hadoop.Īlong with the log files, Flume is also used to import huge volumes of event data produced by social networking sites like Facebook and Twitter, and e-commerce websites like Amazon and Flipkart.įlume supports a large set of sources and destinations types.įlume supports multi-hop flows, fan-in fan-out flows, contextual routing, etc.SAN ANTONIO - There is nothing more frustrating than seeing your water bill skyrocket for a few months and not have a clue as to why. There are currently two release code lines available, versions 0.9.x and 1.x. Apache Flume is a top-level project at the Apache Software Foundation. Some of the notable features of Flume are as follows −įlume ingests log data from multiple web servers into a centralized store (HDFS, HBase) efficiently. Apache Flume is a distributed, reliable, and available system for efficiently collecting, aggregating and moving large amounts of log data from many different sources to a centralized data store. It guarantees reliable message delivery.įlume is reliable, fault tolerant, scalable, manageable, and customizable. ![]() The transactions in Flume are channel-based where two transactions (one sender and one receiver) are maintained for each message. When the rate of incoming data exceeds the rate at which data can be written to the destination, Flume acts as a mediator between data producers and the centralized stores and provides a steady flow of data between them.įlume provides the feature of contextual routing. Using Apache Flume we can store the data in to any of the centralized stores (HBase, HDFS). ![]() If you are looking to purchase a meter that is compatible with Flume we recommend the Neptune T-10 and Badger meters (anything but the Badger E-series which. However, you should check to see if your meter is compatible before you purchase a Flume device. Here, Apache Flume comes to our rescue.įlume is used to move the log data generated by application servers into HDFS at a higher speed. The Flume product is compatible with about 95 of water meters in the United States today. To do so, they would need to move the available log data in to Hadoop for analysis. Applications of FlumeĪssume an e-commerce web application wants to analyze the customer behavior from a particular region. It is principally designed to copy streaming data (log data) from various web servers to HDFS. Apache Flume is a tool/service/data ingestion mechanism for collecting aggregating and transporting large amounts of streaming data such as log files, events (etc.) from various sources to a centralized data store.įlume is a highly reliable, distributed, and configurable tool. Parshall flume sizes are designated by the throat width, W, and dimensions are available for flumes from the 1-in size for free flow of 0.03 ft3/s at 0.2 ft of. ![]()
