With the use of VerdictDB both Presto and BigQuery provided the speed required to allow a human interface to our Data Warehouse, BigQuery out performed Presto in a number of areas especially when BigQuery BI was thrown into the equation, and although this is still in beta offering only 10GB (should be enough to cache a 1% scramble of 1TB of data), it has huge potential in offering a cost-effective and fast interface to Big Data. Naturally, we started with the basics and well known offerings, however, we had a number of different requirements from each Database / Data Warehouse that doesn’t really make this a fair comparison to many of them in a lot of ways (for example we require Geospatial capabilities which ruled out a number of other platforms).

In the example code above this is ensured by enforcing one result via LIMIT 1. BigQuery does include the functionality of table clustering and partitioning to cut down on query costs – in our experience though, these haven’t been truly necessary with marketing datasets. UNIX_MICROS(TIMESTAMP_SUB(CURRENT_TIMESTAMP(), INTERVAL 10 DAY)) There are also several other options that exist that could be used as the query interface once the scrambles are built on Presto!

Google Analytics 360 users that have set up the automatic BigQuery export will rejoice, but this benefit is … Here is a very simplified example of a single row in your BigQuery table: How the UNNEST operator Works UNNEST allows you to flatten the “event_params” column so that each item in the array creates a single row in the table with two new columns: “event_params.key” and “event_params.value”. I have been under the impression that if you were to do a COUNT(DISTINCT xyz) on some GROUP BY and ORDER BY can also refer to a third group: Integer literals, which refer to items in the SELECT list. For more information, see Wrangle Language. Increasing the DISTINCT Approximation Threshold. As stated directly in the official documentation, BigQuery’s implementation of DISTINCTreturns a value that is a “statistical approximation and is not guaranteed to be exact.” Obviously this is for performance reasons and to reduce the cost to the end-user.

Count of sessions by source/medium in BigQuery (last interaction) And now let’s see the numbers using the “last non-direct click” attribution model. BigQuery came out on top for a number of different reasons as the backing data warehouse, however the focus of this is really on what VerdictDB can really provide in terms of simplicity and speed vs traditional methods such as HyperLogLog. HAVING COUNT(event_date) >= 4 We performed this on both Presto and on BigQuery — BigQuery came out cheaper for our particular use case but there are a number of reasons for that (not applicable to this article).
