pgloader loads data into PostgreSQL and allows you to implement Continuous Migration from your current database to PostgreSQL.

pgLoader has two modes of operation. It can either load data from files, such as CSV or Fixed-File Format; or migrate a whole database to PostgreSQL.

pgLoader supports several RDBMS solutions as a migration source, and fetches information from the catalog tables over a connection to then create an equivalent schema in PostgreSQL. This means that you can migrate to PostgreSQL in a single command-line!

Zipkin is a distributed tracing system. It helps gather timing data needed to troubleshoot latency problems in microservice architectures. It manages both the collection and lookup of this data. Zipkin’s design is based on the Google Dapper paper.

Applications are instrumented to report timing data to Zipkin. The Zipkin UI also presents a Dependency diagram showing how many traced requests went through each application. If you are troubleshooting latency problems or errors, you can filter or sort all traces based on the application, length of trace, annotation, or timestamp. Once you select a trace, you can see the percentage of the total trace time each span takes which allows you to identify the problem application.

Jaeger, inspired by Dapper and OpenZipkin, is a distributed tracing system released as open source by Uber Technologies. It is used for monitoring and troubleshooting microservices-based distributed systems, including:

Distributed context propagation
Distributed transaction monitoring
Root cause analysis
Service dependency analysis
Performance / latency optimization
