Exoscale vs QuestDB: at a glance
What is Exoscale?
Exoscale lets customers keep their own encryption keys outside its cloud.
Exoscale, a European cloud provider, opened a private preview of KMS External Key Store on 3 November: customers connect Exoscale KMS to their own HSM or key manager through a proxy they host, and Exoscale never sees the key material. It implements the AWS KMS XKS proxy API, so existing proxies work unchanged. This follows a free VPC in every zone in October, object-storage lifecycle rules, asymmetric KMS keys and cheaper IPv6 load balancing.
What is QuestDB?
QuestDB keeps proving its market-data case with reproducible benchmarks between releases.
QuestDB 10.1 and Enterprise 4.1 are the October product releases: merge-append partitions for late data, SUBSAMPLE and exact percentiles, then resource groups, audited views and OIDC for shared clusters. The newest entry is a benchmark rather than a release, replaying 354 million top-of-book events for a full US equities day as Arrow, with memory and throughput figures and rerunnable code. The rest of the feed is technical content on joins, Parquet and QWP compression.

Exoscale lets customers keep their own encryption keys outside its cloud.
◆ Current state
Exoscale, a European cloud provider, opened a private preview of KMS External Key Store on 3 November: customers connect Exoscale KMS to their own HSM or key manager through a proxy they host, and Exoscale never sees the key material. It implements the AWS KMS XKS proxy API, so existing proxies work unchanged. This follows a free VPC in every zone in October, object-storage lifecycle rules, asymmetric KMS keys and cheaper IPv6 load balancing.
◆ Where it's heading
KMS has moved fast: asymmetric keys in early October, external keys four weeks later. Together with VPC and lifecycle rules, Exoscale is closing gaps against the hyperscalers, and XKS points its pitch at sovereignty-bound customers who need to prove the provider cannot decrypt their data.
◆ Prediction
XKS will likely widen from private preview to general availability, and the next steps are probably more services encrypting with KMS keys; the entries don't say which services or when.
QuestDB
5.0DEVOPS
QuestDB keeps proving its market-data case with reproducible benchmarks between releases.
◆ Current state
QuestDB 10.1 and Enterprise 4.1 are the October product releases: merge-append partitions for late data, SUBSAMPLE and exact percentiles, then resource groups, audited views and OIDC for shared clusters. The newest entry is a benchmark rather than a release, replaying 354 million top-of-book events for a full US equities day as Arrow, with memory and throughput figures and rerunnable code. The rest of the feed is technical content on joins, Parquet and QWP compression.
◆ Where it's heading
The release work and the content point the same way: QuestDB as the shared store for trading data, read by many teams and many engines. Enterprise features govern how a cluster is shared, while the posts show the data leaving QuestDB through Parquet and Arrow at volume.
◆ Prediction
Expect the next release to target read-out paths such as Arrow streaming or Parquet export, since the benchmarks are already measuring them; the entries do not show a date.
