A query endpoint interpolates client-provided JSON paths and operators into SQL.
Estimated field mix
The database query for arrays and null values differs subtly from the API contract, making support reports inconsistent.
Estimated field mix
New readers assume every document has a valid owner and UTC creation instant, but quarantined legacy rows still violate that assumption.
Estimated field mix
The team wants to remove legacy JSON fields immediately after switching reads, which could break old clients during a rollback.
Estimated field mix
The scheduler table stores only owner name and expiry, so an old owner can appear identical to a later process with the same name.
Estimated field mix
Two instances disagree about lease expiry because their local clocks differ by several seconds.
Estimated field mix
The design adds a lease but assumes every downstream operation automatically knows whether its caller is still leader.
Estimated field mix
Two instances see an expired lease and both believe they became the active scheduler.
Estimated field mix
A delayed renewal from an earlier process extends the newest owner's lease row while reporting success to the stale process.
Estimated field mix
A scheduler pauses past expiry, then resumes a previously prepared plan after another instance has taken over.
Estimated field mix
A new leader repeats the current maintenance period and creates a second plan for the same logical occurrence.
Estimated field mix
A scheduler renews its lease while stuck on one task, so the status page incorrectly reports healthy processing.
