In most datasets with a large number of events, going through individual events is less important. Most of the data use cases are around the summarized data. Druid summarizes this raw data at ingestion time using a process refer to as “roll-up”. Roll-up is the highest granularity of the data and will be able to query only up to the roll-up granularity. However, there are some scenarios where it’s important to have more granular data. However keeping more granular data comes at a cost. We did a small experiment to identify how different roll-up levels affect performance.
Rolling up data can dramatically reduce the size of data that needs to be stored (up to a factor of 100). Druid will roll up data as it is ingested to minimize the amount of raw data that needs to be stored. This storage reduction does come at a cost; as we roll up data, we lose the ability to query individual events. Phrased another way, the rollup granularity is the minimum granularity you will be able to explore data at and events are floored to this granularity. Hence, Druid ingestion specs define this granularity as the queryGranularity of the data. The lowest supported queryGranularity is millisecond. -http://druid.io
Dataset and Setup
We choose a CSV data set with millions (150M+) of records which contain sales data spanning across 2 years. CSV file was around 6 GB in physical size. This is a narrow data set with 3 dimensions and 2 metrics. We had 2 servers where all the components are deployed.
m4 large – Coordinator, Brokers, Overload nodes
r3 large – Middle managers and Historical nodes
We all come across some situations where some electronic features are not working suddenly. Most of the time it relates to a blown fuse. In this article, we talk about how to identify and replace a blown fuse. When doing this, it is always recommended to have a good idea about what functionalities relate to each fuse. So mainly in this article, we will talk about Suzuki WagonR Hybrid fuse design.
Where can we find the fuses in Suzuki WagonR Hybrid?
Mainly fuses found in five places. However, we are talking about three out five places where you will find fuses related to electronic accessories.
