What is the current estimated delivery date for order bench-852b72d4?

Expected Answer: 2024-01-15

PostgreSQL PASS

Based on the query results, I found that the estimated delivery date for order 'bench-852b72d4' is 2024-01-15. The key was in the 'delivery_date' field, not 'estimated_delivery_date' as initially assumed. So the current estimated delivery date for this order is January 15, 2024.

3,584 tokens 9.3s

PostgreSQL+CDC PASS

Based on the query results, the current estimated delivery date for order bench-852b72d4 is 2024-01-15. The initial query returned null for 'estimated_delivery_date', but the second query revealed that the delivery date is stored under the key 'delivery_date' in the after_state JSON. The most recent CDC event shows the delivery date as January 15, 2024.

2,872 tokens 7.3s

KurrentDB PASS

Based on the stream events, the current estimated delivery date for order bench-852b72d4 is 2024-01-15. The events show a progression from the original delivery date of 2024-02-20 to a new delivery date of 2024-01-15, with the reason cited as "warehouse_backlog". The stream contains three events related to order placement, shipping, and a delivery delay, all consistently showing the updated delivery date of 2024-01-15.

Expected Answer: 20420.50

PostgreSQL FAIL

After multiple investigations, I can conclude that for the account 'bench-a07b149f': 1. The current balance is 92,100.00 2. There is no transaction history stored in the available data 3. I cannot definitively determine the balance before the last transaction The most precise answer I can provide is the current balance of 92,100.00, but I cannot retrieve the previous balance due to lack of transaction data in the accessible tables.

15,706 tokens 27.5s

PostgreSQL+CDC PASS

Based on the query results, the balance of account bench-a07b149f before the last transaction was $20,420.50. A few observations: - The operation (op) is 'u', which typically indicates an update - The timestamp (ts_ms) shows this was the most recent event - The previous_balance represents the balance before the last transaction was applied Is there anything else you would like to know about this account?

1,822 tokens 5.6s

KurrentDB PASS

Based on the stream events, I can answer your specific question: The balance of account bench-a07b149f before the last transaction was $20,420.50. The most recent event shows a transfer with the following details: - Previous balance: $20,420.50 - Current balance: $92,100.00 - Reason for transfer: insurance_premium So the balance before the last transaction (which appears to be an insurance premium payment) was $20,420.50.

I found the record, but the delay is stored differently than I initially expected. The total delay is directly specified in the 'delay_minutes' field. The total delay for flight 'bench-b9d11258' is 180 minutes (3 hours). To break this down: - The flight has a total accumulated delay of 180 minutes - This is stored directly in the 'delay_minutes' field of the JSONB data - The specific causes of delay are not individually broken down in this record

Crew-related delay: Added 60 minutes 4. Air Traffic Control (ATC) delay: Added 75 minutes Total accumulated delay: 180 + 45 + 60 + 75 = 360 minutes (6 hours) The flight experienced significant delays across multiple causes: - Initial delay: 180 minutes - Weather delay: 45 minutes - Crew delay: 60 minutes - ATC delay...

Let me calculate the total delay by summing the delay_added values: - Weather delay: 45 minutes - Crew delay: 60 minutes - ATC (Air Traffic Control) delay: 75 minutes Total accumulated delay: 45 + 60 + 75 = 180 minutes (3 hours) This matches the 'current.delay_minutes' value of 180 minutes across the events. The flight experienced a total delay of 3 hours due to a combination of weather, crew, and air traffic control issues, which were described as "cascading_delays".

Expected Answer: draft

PostgreSQL FAIL

Unfortunately, while the state is confirmed, the additional details like title, creation date, and closing date appear to be null in the database. The key information is that the pull request was in a "closed, not merged" state before being closed.

Based on the query results, I can provide the following details: Before the pull request was closed, its state was "draft". The CDC event shows: - Initial state (before_state): "draft" - Final state (after_state): "closed, not merged" So to directly answer your question: The state of PR bench-29e08d6a before it was closed was "draft".

1,796 tokens 4.5s

KurrentDB PASS

Based on the stream events, I can confidently answer that the state of the pull request before it was closed was "draft". The first event shows the transition from the "draft" state to "closed, not merged" state. Specifically: - Previous state: draft - Current state: closed, not merged - Reason for closure: merged_manually So the pull request was in a draft state before being closed and marked as "not merged".

The CDC event shows: - The initial state had "diverted" as "no" - A subsequent update (op: "u" meaning update) changed the diverted status to "yes, ORD" So the flight was originally not diverted, but was later diverted to Chicago O'Hare International Airport.

What was the original rating for movie bench-526661a4?

Expected Answer: 1.5

PostgreSQL FAIL

The original rating for movie 'bench-526661a4' is 3.0 out of 5. This result was obtained by directly querying the movielens.ratings table, selecting the 'rating' field from the JSONB data column for the specific movie ID you mentioned. The rating is a numeric value of 3.0, which typically indicates an average or moderate rating on a 5-point scale.

1,576 tokens 4.7s

PostgreSQL+CDC PASS

Based on the query results, the original rating for movie bench-526661a4 was 1.5. The CDC event shows: - Original Rating: 1.5 - Current Rating: 3.0 - Operation: Update (u) - Timestamp: 1771420246100 The rating was updated from 1.5 to 3.0 at the specified timestamp.

KurrentDB PASS

Based on the stream events, the original rating for movie bench-526661a4 was 1.5. In the first event (rating.created), the 'previous' field shows a rating of 1.5, which represents the original rating before any updates. The rating was then updated to 3.0 with the reason "director_cut_superior" in both the first and second events. So, the original rating for the movie was 1.5.

I found the record, but it appears the delay is stored differently than I initially expected. The total delay is directly specified in the 'delay_minutes' field. The total delay for flight 'bench-c1ad6cf4' is 180 minutes. To break this down: - The flight has a total delay of 180 minutes - The delay details are stored in a simplified format in this dataset - The specific breakdown of delay causes is not provided in this record

4,276 tokens 11.3s

PostgreSQL+CDC FAIL

Interesting! The total accumulated delay is actually 1080 minutes (18 hours), which is significantly more than the initial observation. To provide a complete answer: The flight 'bench-c1ad6cf4' accumulated a total delay of 1080 minutes (18 hours) across multiple CDC events. Each event shows an increase from 0 to 180 minutes, and these events have accumulated to a total of 1080 minutes of delay.

3,923 tokens 11.2s

KurrentDB PASS

Let me calculate the total delay by summing the delay_added values: - Weather delay: 45 minutes - Crew delay: 60 minutes - ATC (Air Traffic Control) delay: 75 minutes Total accumulated delay: 45 + 60 + 75 = 180 minutes (3 hours) This matches the final 'current.delay_minutes' value of 180 minutes in the events. The flight experienced a total delay of 180 minutes (3 hours) due to a combination of weather, crew, and air traffic control issues.

After thorough investigation, I cannot definitively answer whether the user removed the movie from their watchlist because: 1. The rating data is incomplete 2.
