What's changing: PowerSync Service relabels Azure DocumentDB source support from "experimental" to "alpha," now that Azure DocumentDB respects maxAwaitTimeMS on getMore. The client-side idle-polling delay workaround (capped at 1 second) that compensated for DocumentDB previously not respecting that timeout has been removed, since it's no longer needed.
High priority — existing docs are now inaccurate or incomplete
- Feature Status (https://docs.powersync.com/resources/feature-status), "Feature Status Summary" table: lists "Azure DocumentDB (Cosmos DB for MongoDB vCore)" as "Experimental." This is now inaccurate — support is now alpha.
- Source Database Setup (https://docs.powersync.com/configuration/source-db/setup#azure-documentdb): the MongoDB section's note describes DocumentDB as "an [experimental] feature," and the "Azure DocumentDB" subsection opens with a Warning stating "Azure DocumentDB support is experimental." Both are now inaccurate. The same subsection's "Limitations to Check Before You Connect" list also states that streaming updates can be delayed by up to roughly 1 second after an idle period because of "a temporary workaround" that is "expected to be resolved in an upcoming Azure DocumentDB release." That workaround has now been removed from PowerSync's implementation, so this limitation no longer applies and the bullet is now incorrect.
- Source Database Connection (https://docs.powersync.com/configuration/source-db/connection#azure-documentdb-specifics), "Azure DocumentDB Specifics" section: states "Azure DocumentDB support is [experimental]." Now inaccurate.
- PowerSync Overview (https://docs.powersync.com/intro/powersync-overview): the database connector card reads "Azure DocumentDB (Experimental)." Now inaccurate.
For reviewer consideration — worth documenting
