What is prova?
prova adds expected-utility calculation on top of its Bayesian inference core.
prova does Bayesian nonparametric inference in R — probabilities through Pr() and qPr(), mutual information, quantile plots. Five releases in about two weeks renamed its central argument, collapsed two plotting functions into one, and then in v2.3.0 introduced exputility() for expected utilities and their revisability, with plot() and print() methods attached from the start.
What is SigNoz?
Search without knowing the field — SigNoz keeps lowering the cost of not knowing your schema
SigNoz is an OpenTelemetry-native observability platform, and its recent quarter runs on two threads: compatibility as a migration argument, and agent-readiness. The dashboard rebuild on the CNCF Perses specification was the clearest statement of the second. The newest release adds a search() function to the Logs Explorer that matches a literal, case-insensitive term across body, attribute and resource keys and values without the user knowing which field holds it, optionally narrowed to named field contexts.

prova

prova adds expected-utility calculation on top of its Bayesian inference core.
◆ Current state
prova does Bayesian nonparametric inference in R — probabilities through Pr() and qPr(), mutual information, quantile plots. Five releases in about two weeks renamed its central argument, collapsed two plotting functions into one, and then in v2.3.0 introduced exputility() for expected utilities and their revisability, with plot() and print() methods attached from the start.
◆ Where it's heading
Two arcs run in parallel. One compresses the API: learnt= became K=, flexiplot() and plotquantiles() merged into pplot(), and omitting arguments such as Y=, X= and K= got simpler. The other extends reach — mutualinfoF() for finite-domain variates, quantile accuracy reported alongside mutual information, and now a decision-theoretic layer sitting on the inference the package already did.
◆ Prediction
exputility() shipping with print() and plot() methods matches how the probability and mutual-information classes were treated, so utilities are likely to get the same class-based handling as they mature. The notes do not say whether decision analysis extends beyond expected utility.

Search without knowing the field — SigNoz keeps lowering the cost of not knowing your schema
◆ Current state
SigNoz is an OpenTelemetry-native observability platform, and its recent quarter runs on two threads: compatibility as a migration argument, and agent-readiness. The dashboard rebuild on the CNCF Perses specification was the clearest statement of the second. The newest release adds a search() function to the Logs Explorer that matches a literal, case-insensitive term across body, attribute and resource keys and values without the user knowing which field holds it, optionally narrowed to named field contexts.
◆ Where it's heading
Both threads keep advancing. PromQL conformance and an open dashboard schema lower the cost of moving to SigNoz from whatever is already installed; full-text search lowers the cost of not yet knowing your own telemetry schema, which is the same argument aimed at a new user's first hour rather than at a migration. Integration onboarding keeps expanding at a weekly clip, and the v1 alert history endpoints are running against an announced deadline.
◆ Prediction
Expect the schema-first treatment to reach alerts and saved views next, and the v1 alert history endpoints to disappear within a release or two; since search()'s own notes steer users toward field filters once the schema is known, field-context narrowing is the likely place it gets faster.
