| ESCA-341 | A streaming event ticker endpoint has been created. This enables adding multiple named filters, which can be used to associate events with the groups in the UI. |
| ESCA-342 | Optimised queryKeys by moving the join to the Names table last in the query plan. |
| ESCA-343 | Removed the redundant join when the EntityFilter is empty. |
| ESCA-345 | The index now only scans for GetEntitySeverity, which reduces the amount of data needed. |
| ESCA-346 | Removed the following unused fields: EntitySummaryStatistics.entity_count_unclassified_roots from the API and is_root from the database schema. |
| ESCA-348 | Improved index performance by batch inserting the attribute history |
| ESCA-349 | Default PostgreSQL CPU settings have been updated. |
| ESCA-363 | Optimised the SignalFilter by doing a pre-lookup on signalId, which avoids a join at query time. |
| ESCA-367 | Optimised EntityKeyPivotBuilder used by the Overview app to query the grouped entity statistics. |
| ESCA-368 | Consecutive NONE signals are dropped since they are of no interest to the Query Service, freeing up storage space. |
| ESCA-370 | A unique index for the Signals table has been added, which resolves an issue where the table could contain duplicated rows if the sink is restarted. |
App Query Service 1.4.0 Copied
Released: 9 November 2022
New features and enhancements Copied
These are the new features and enhancements of this release:
| Issue key | Release description |
|---|---|
| ESCA-310 | Optimised storage of signals in the App Query Service, which now stores repeated namespaces and names only once. |
| ESCA-316 | Memory thresholds can now be manually configured. |
| ESCA-317 | The table and index sizes for the entity attributes table have been reduced by 30%. |
| ESCA-333 | The QueryEntityInfo database query has been optimised to reduce the number of database calls. The query is now executed as a single query, which has dropped the execution time from 2 to 3 seconds to ~400 ms. |
| ESCA-335 | To take type alignment into account and reduce table size, columns in tables have been reordered. |
App Query Service 1.3.0 Copied
Released: 17 October 2022
New features and enhancements Copied
These are the new features and enhancements of this release:
| Issue key | Release description |
|---|---|
| ESCA-299 | The App Query Service getDimensionTable endpoint, which is used by the dimension table displayed in the Alerting app, has been updated to hide the final dimension key if the optional label is the same. |
| ESCA-300 | A database trigger for signals has been replaced with a cache for faster inserts. |
| ESCA-302 | To optimise insert performance, fsync and full_page_writes have been turned off. By disabling PostgreSQL durability features and guarantees, App Query Service is bootstrapped from the ITRS Analytics Platform on start-up and can deal with a corrupted state. |
| ESCA-303 | Unlogged tables are now used to improve insert performance. |
| ESCA-307 | PostgreSQL settings are now automatically adjusted based on available memory. |
App Query Service 1.2.0 Copied
Released: 4 October 2022
New features and enhancements Copied
These are the new features and enhancements of this release:
| Issue key | Release description |
|---|---|
| ESCA-286 | Entities that have a severity status or are snoozed now get indexed regardless of their age to ensure that Overview app data (tree view) remains consistent. |
| ESCA-292 | The materialised hierarchy view has been removed. This improves performance since the view consumes a lot of CPU resources and takes a long time to update when there is a large number of entities in the system. |
| ESCA-294 | The QuerySignalInfo endpoint has been removed since the Alerting app now uses new endpoints which are based on the ITRS Analytics Platform attribute history. |
| ESCA-296 | Free-text search no longer searches for descendants. This feature has been removed since it causes performance issues in the App Query Service. |
| ESCA-297 | The SQL query for free-text search has been optimised. |

App Query Service 1.1.0 Copied
Released: 23 August 2022
New features and enhancements Copied
These are the new features and enhancements of this release:
| Issue key | Release description |
|---|---|
| ESCA-253 | Timelines and signals in the QuerySignalInfo endpoint are now exposed. By adding the timeline to QuerySignalInfosResponse, requests to the backend are lessened. |
| ESCA-256 | Bucketed timelines for individual signals are now exposed. This allows the retrieval of bucketed signal timelines for a single entity. |
| ESCA-259 | Configuration changes related to WAL data tuning as well as calculating settings based on Kubernetes resources have been implemented for improved performance. |
| ESCA-260 | When entities get evicted from the ITRS Analytics Platform, the App Query Service also evicts the said entities to ensure consistency. |
| ESCA-261 | JOOQ SQL queries and timing are now logged, which can help in diagnosing performance issues. |
| ESCA-264 | GetLatestMetricValues has been added to the API, which can be used to request metrics for direct descendants of an entity. |
| ESCA-266 | To enable metrics collection by the Kubernetes plugin, the following environment variables have been added to PostgreSQL deployment: NODE, NAMESPACE, POD, and CONTAINER. |
| ESCA-270 | To improve resource handling, the main daemon has been split into two separate processes: subscribe to entities and upsert in the DB container (write) and query the DB container for requests from the front-end (read). |
