Fusion Data Store requires a peak of approximately 6GB of server memory per 50 million observations:
120MB per million observations.


  • The balance between series and observations will also affect memory requirements with datasets where each series has few observations needing additional memory.
  • The figures quoted above are peak memory requirements when updating or replacing existing datasets. Quiescent memory requirements are lower.
  • Services such as Fusion Registry have additional memory requirements which need to be taken into account when sizing deployment platforms such as the volume of stuctural metadata.
