Aiven vs QuestDB
A side-by-side editorial comparison of Aiven and QuestDB — release velocity, themes, recent moves, and the top alternatives to consider.
Aiven vs QuestDB: at a glance
What is Aiven?
Aiven moves Grafana to 13 and gives Runtime apps custom domains.
Aiven's November releases mix pricing changes with plumbing between its own services. The MySQL free tier stops on 21 December, bring-your-own-key encryption is included at no extra cost, and a change-data-capture integration now copies PostgreSQL tables into ClickHouse in limited availability. On 12 November Grafana 13.2 became available alongside 12.4, without Git Sync or the Synthetic Monitoring app, and Aiven Runtime applications gained custom domains and readable URLs.
What is QuestDB?
QuestDB 10.2 adds a power-loss durability mode for WAL tables.
QuestDB 10.1 and Enterprise 4.1 were the October releases: merge-append partitions for late data, SUBSAMPLE and exact percentiles, then resource groups, audited views and OIDC for shared clusters. QuestDB 10.2 follows with a power-loss durability mode for WAL tables, GROUPING SETS, passthrough views with row-level retention and a DEDUP SKIP mode that keeps the first copy of a row. Between releases the feed runs benchmarks and how-tos, most recently live port congestion from free AIS ship data.
Aiven vs QuestDB: editorial side-by-side
Aiven
6.3DEVOPS
Aiven moves Grafana to 13 and gives Runtime apps custom domains.
◆ Current state
Aiven's November releases mix pricing changes with plumbing between its own services. The MySQL free tier stops on 21 December, bring-your-own-key encryption is included at no extra cost, and a change-data-capture integration now copies PostgreSQL tables into ClickHouse in limited availability. On 12 November Grafana 13.2 became available alongside 12.4, without Git Sync or the Synthetic Monitoring app, and Aiven Runtime applications gained custom domains and readable URLs.
◆ Where it's heading
Aiven is filling out the layer around its databases: logs, access control, encryption, dashboards and now an application runtime with its own domains. Each release is small, but together they make it easier to keep both data and the apps that use it on Aiven.
◆ Prediction
Expect more Aiven Runtime features that connect apps to Aiven's own databases, and a default-version switch to Grafana 13 once 12.4 nears end of support.
QuestDB
5.0DEVOPS
QuestDB 10.2 adds a power-loss durability mode for WAL tables.
◆ Current state
QuestDB 10.1 and Enterprise 4.1 were the October releases: merge-append partitions for late data, SUBSAMPLE and exact percentiles, then resource groups, audited views and OIDC for shared clusters. QuestDB 10.2 follows with a power-loss durability mode for WAL tables, GROUPING SETS, passthrough views with row-level retention and a DEDUP SKIP mode that keeps the first copy of a row. Between releases the feed runs benchmarks and how-tos, most recently live port congestion from free AIS ship data.
◆ Where it's heading
Releases are filling in what a production database needs beyond raw speed: crash safety, broader SQL and data retention controls. The content keeps the market-data focus while reaching into other streams such as ship tracking.
◆ Prediction
Expect another 10.x release within weeks, likely more SQL coverage, while Enterprise picks up the retention and durability features for shared clusters.
