What is capacitor in BigQuery?
Capacitor — the storage format in BigQuery, builds heavily on this research and employs variations and advancements of these techniques. To show one example where Capacitor advances the state of the art, we'll review the problem of reordering of input rows. This is one of the less studied problems in research (see this paperfor some background).
What's new in the capacitor file format?
The Capacitor file format incorporates new features to enhance performance: Partition and predicate pruning: Various statistics are maintained about the values in each column, which are used to eliminate partitions that are guaranteed not to contain any matching rows.
What is a capacitor approximation model?
Capacitor builds an approximation model that takes into account all relevant factors and comes up with a reasonable solution. The runtime of evaluating this model is bound, since we wouldn’t want data import to BigQuery to take forever!
How does capacitor handle nested data?
Nested Data : BigQuery supports complex, nested data structures. Capacitor handles this by storing each column in separate files, allowing for fast access and processing. 2.
What does BigQuery data look like?
Overall the organisation of data looks like below: BigQuery, on the other hand, uses columnar storage, where each column is stored in a separate area on the residing disk. The chunk of data stored on disks is otherwise fondly known as Capacitors. In simple words, capacitor is the file format of storage on Colossus system for BigQuery data.
What is capacitor & how does it work?
As defined, Capacitor is a column-oriented format — this means, the values of each field are stored separately, so the overall I/O overhead (during any or all of the read and write operations) is proportional to the number of fields you actually read!

Another popular type of capacitor is an electrolytic capacitor. It consists of an oxidized metal in a conducting paste. The main advantage of an electrolytic capacitor is its high capacitance relative to other common types of capacitors. For example, capacitance of one type of aluminum electrolytic capacitor can be as high as 1.0 F. However, you must be careful …
