The short version

  • Only Elasticsearch has a free tier, so it costs nothing to try first.
  • Each has a real cost: Celonis no pricing is published anywhere on the site; the only path to a quote is a Contact Us sales form requiring company details, with no self-serve signup or published starting price; Elasticsearch eventual consistency model with 1-second default refresh interval, not suitable for real-time transactional requirements

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Celonis

  • No pricing is published anywhere on the site; the only path to a quote is a Contact Us sales form requiring company details, with no self-serve signup or published starting price
  • The vendor's own contact page directs prospects to wait for a Celonis representative to get in touch rather than offering instant access

Elasticsearch

  • Eventual consistency model with 1-second default refresh interval, not suitable for real-time transactional requirements
  • No support for ACID transactions or rollbacks; updates delete and re-insert documents
  • JVM-dependent architecture requires careful memory management and monitoring to prevent garbage collection issues at scale

Elasticsearch: Can I use Elasticsearch without Kibana?

Yes, Elasticsearch is a search engine independent of Kibana. Kibana is a visualization and analytics tool that works with Elasticsearch but is optional. You can use the Elasticsearch API directly for searching.

Source
Elasticsearch: Does Elasticsearch support real-time indexing?

Elasticsearch indexes data with a refresh interval, typically 1 second. Data becomes searchable after the refresh cycle, making it near-real-time but not instantaneous. This can be configured but impacts performance.

Source
Elasticsearch: What are Elasticsearch's scaling limitations?

Elasticsearch requires careful operational management at scale, including shard balancing, heap sizing, and monitoring. Large clusters can suffer from garbage collection issues and become expensive to operate.

Source
Elasticsearch: Does Elasticsearch support transactions and rollbacks?

No, Elasticsearch does not support ACID transactions or rollbacks. Updates are expensive operations that delete and re-insert documents, making it unsuitable for transactional workloads.
