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 Sanity?

Sanity's MCP server now explains failed validations and stops skipping them.

Sanity made Context Knowledge Bases generally available on November 10, letting agents read datasets, websites and files over MCP. The days since have been follow-up: MCP server 2.46.1 and 2.46.2 return stable error codes, explain incomplete validations and stop writes from skipping schema checks, while the console now shows when each robot token was last used. Media Library made PDF previews zoomable and folder counts in big libraries about seven times faster.

QuestDB vs Sanity: editorial side-by-side

Q
QuestDB
DEVOPS
5.0

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.

6.3

Sanity's MCP server now explains failed validations and stops skipping them.

◆ Current state

Sanity made Context Knowledge Bases generally available on November 10, letting agents read datasets, websites and files over MCP. The days since have been follow-up: MCP server 2.46.1 and 2.46.2 return stable error codes, explain incomplete validations and stop writes from skipping schema checks, while the console now shows when each robot token was last used. Media Library made PDF previews zoomable and folder counts in big libraries about seven times faster.

◆ Where it's heading

Sanity is making the agent-facing parts dependable: the MCP server is getting the error codes and validation rules a production client needs. Access visibility for tokens and members follows the same push to let teams audit what automated clients do.

◆ Prediction

Expect more MCP server point releases around validation and Knowledge Base commands, and more usage data on tokens and agents in the console.
