ELO moves real-time payments analytics from Elasticsearch to ClickHouse

A ClickHouse technical account published in April 2026 describes Nava’s completed migration of ELO’s real-time payments-monitoring analytics from Elasticsearch to ClickHouse.

Historical record: This page predates PlatformTrace’s 25 July 2026 Ireland and United Kingdom scope. It is preserved for citation and correction history, but is excluded from active counts, search results and current market coverage. Read the archive policy.
Evidence boundary: The bounded analytics workload is operational on ClickHouse, but the evidence does not show that every ELO Elasticsearch workload was retired.

What was reported

The production account covers approximately 22 million transactions per day, 300 real-time dashboards and reported storage and infrastructure-cost reductions.

Verified facts

  • Elasticsearch is the source analytics platform and ClickHouse is the destination.
  • The workload processes approximately 22 million financial transactions per day.
  • The reported storage footprint fell from 12 TB to 2 TB.
  • Approximately 300 dashboards refresh every five seconds with sub-two-second Kafka-to-visualisation latency.

What is not established

  • The exact production cutover date is not stated.
  • The visualisation product is not named.
  • The reported annual cost reduction is not independently audited and does not enumerate every cost component.

PlatformTrace analysis

This is a completed migration of a bounded operational analytics workload, not evidence that ELO eliminated all Elasticsearch usage.
