Cortex vs Displayr: at a glance
What is Cortex?
Cortex 1.22 is on its fourth candidate, with sharded Parquet and years of deprecated flags removed.
Cortex 1.22.0 has been in release candidates since 12 September, reaching rc.3 on 6 October, and GitHub shows no final yet. The candidate adds sharded Parquet conversion and querying, resource-based query eviction that cancels the heaviest query when CPU or heap crosses a threshold, OCI Object Storage as a backend, and an active-series tracker per tenant. It also removes long-deprecated flags and config fields, some of which now stop Cortex from starting if left in place.
What is Displayr?
Displayr's Chat can now apply and write Rules, so it changes tables as well as explaining them.
Rules, Displayr's mechanism for customizing a table's appearance and data, now work through Chat: it applies existing rules and writes custom ones, and a rule can cover every table in a document, including new ones. Two smaller additions landed with it at the end of September: document duplication through the API and a shortcut from a control to its input. Summer work made Chat auditable, with a context pill, a change summary and an Explain This button, while the core gained shared controls and rolling averages.

Cortex 1.22 is on its fourth candidate, with sharded Parquet and years of deprecated flags removed.
◆ Current state
Cortex 1.22.0 has been in release candidates since 12 September, reaching rc.3 on 6 October, and GitHub shows no final yet. The candidate adds sharded Parquet conversion and querying, resource-based query eviction that cancels the heaviest query when CPU or heap crosses a threshold, OCI Object Storage as a backend, and an active-series tracker per tenant. It also removes long-deprecated flags and config fields, some of which now stop Cortex from starting if left in place.
◆ Where it's heading
The storage arc toward Parquet continues: after 1.21 made Parquet a Store Gateway query mode, 1.22 shards files that exceed column limits. A second arc is protecting shared clusters from heavy tenants, through query eviction, resource-based throttling and concurrent data-byte limits on store gateways. The cleanup is the maturity arc from 1.21 carried further: no-op flags that were tolerated for releases now fail at startup.
◆ Prediction
1.22.0 final should follow rc.3, which added only two fixes. Operators should expect upgrade failures from leftover deprecated flags, and the release notes tell them to grep runtime configs before upgrading.
Displayr
0.0ANALYTICS
Displayr's Chat can now apply and write Rules, so it changes tables as well as explaining them.
◆ Current state
Rules, Displayr's mechanism for customizing a table's appearance and data, now work through Chat: it applies existing rules and writes custom ones, and a rule can cover every table in a document, including new ones. Two smaller additions landed with it at the end of September: document duplication through the API and a shortcut from a control to its input. Summer work made Chat auditable, with a context pill, a change summary and an Explain This button, while the core gained shared controls and rolling averages.
◆ Where it's heading
Chat is starting to do work that changes results, which tests the auditing features built over the summer. The other track stays steady, closing gaps a long-standing survey analysis platform accumulates. API document duplication hints at more automated reporting workflows, though it is a single endpoint so far.
◆ Prediction
Expect the change summary to extend to rules Chat writes, since a rule applied across a document is harder to inspect than a single edit. Folder-scoped defaults still look like the start of broader template governance.
