Working With Filesystem in Time Series Database

Roman will discuss building a high-performance, open-source time series database in Go, handling massive ingestion rates. He’ll cover techniques for write-heavy systems, including reducing write amplification, instant snapshots, crash protection, WAL tradeoffs, and improving NFS reliability, with real code examples from open-source projects.

Time Series databases face the significant challenge of processing vast amounts of data. At VictoriaMetrics, we are actively developing an open-source Time Series database entirely from scratch using Go. Our average installation handles between 2 to 4 million samples per second during ingestion, with larger setups managing over 100 million samples per second on a single cluster.
In his presentation, Roman will explore various techniques essential for constructing write-heavy applications such as:
  • - Understanding and mitigating write amplification.
  • - Implementing instant database snapshots.
  • - Safeguarding against data corruption post power outages.
  • - Evaluating the advantages and disadvantages of utilizing Write Ahead Log.
  • - Enhancing reliability in Network File System (NFS) environments.
Throughout the talk, Roman will illustrate these concepts with real code examples sourced from open-source projects.
