What is ElephantDB?

ElephantDB is a database that provides an API for reading key/value data from Hadoop. ElephantDB server does not support random writes.

What is Lambda box?

Lambda architecture is an approach to big data management that provides access to batch processing and near real-time processing with a hybrid approach. The basic architecture of Lambda has three layers: Batch, speed and serving. Alongside this slower layer, new data is captured and processed as it comes in.

What is Lambda architecture good for?

Batch layer of Lambda architecture manages historical data with the fault tolerant distributed storage which ensures low possibility of errors even if the system crashes. It is a good balance of speed and reliability. Fault tolerant and scalable architecture for data processing.

What is a speed Layer?

The speed layer processes data streams in real time and without the requirements of fix-ups or completeness. This layer sacrifices throughput as it aims to minimize latency by providing real-time views into the most recent data.

Is PostgreSQL free to use?

Why is it called Lambda Architecture?

These properties of immutability and pure functions are the core tenets of functional programming which in turn has its origins in Alonzo Church’s Lambda Calculus. Because of this Nathan Marz must have named this architecture Lambda Architecture.

What is Lambda pattern?

Abstract. Lambda architecture is a data-processing design pattern to handle massive quantities of data and integrate batch and real-time processing within a single framework.

What is lambda in data?

Back to glossary Lambda architecture is a way of processing massive quantities of data (i.e. “Big Data”) that provides access to batch-processing and stream-processing methods with a hybrid approach. Lambda architecture is used to solve the problem of computing arbitrary functions.

Is PostgreSQL safe?

PostgreSQL generally uses little CPU, RAM or disk I/O unless it’s actually being used for serious work, so it’s fairly safe to ignore it.

How expensive is PostgreSQL?
