QuestDB vs Appsmith: at a glance
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.
What is Appsmith?
Appsmith 2.7 makes its MCP agent ask before deleting widgets and blocks stale edits.
Appsmith v2.7.0, released November 12, mostly extends the embedded MCP server: removing widgets now needs the user's approval, layout updates are refused if the page changed since the agent read it, and agents can build conditional forms, read editor-written JS objects and hide pages. It also adds Table auto height, tightens permissions for custom JS libraries and forking, and applies the restricted-host policy to S3 and DynamoDB datasources. Helm probe defaults and navigateTo behaviour change on upgrade.

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.
Appsmith
5.0DEVOPS
Appsmith 2.7 makes its MCP agent ask before deleting widgets and blocks stale edits.
◆ Current state
Appsmith v2.7.0, released November 12, mostly extends the embedded MCP server: removing widgets now needs the user's approval, layout updates are refused if the page changed since the agent read it, and agents can build conditional forms, read editor-written JS objects and hide pages. It also adds Table auto height, tightens permissions for custom JS libraries and forking, and applies the restricted-host policy to S3 and DynamoDB datasources. Helm probe defaults and navigateTo behaviour change on upgrade.
◆ Where it's heading
Since Appsmith AI shut down in September, the MCP server has become the product's AI strategy: each release widens what outside agents can build and adds guardrails on what they can break. Security hardening of permissions and datasources runs alongside in every release.
◆ Prediction
Expect more MCP tools behind user approval and further 2.7.x patches for the Helm probe and navigateTo changes, as followed earlier minor releases.
