Compressed Big Decimal is an extension which provides support for Mutable big decimal value that can be used to accumulate values without losing precision or reallocating memory. This type helps in absolute precision arithmetic on large numbers in applications, where greater level of accuracy is required, such as financial applications, currency based transactions. This helps avoid rounding issues where in potentially large amount of money can be lost. Accumulation requires that the two numbers have the same scale, but does not require that they are of the same size. If the value being accumulated has a larger underlying array than this value (the result), then the higher order bits are dropped, similar to what happens when adding a long to an int and storing the result in an int. A compressed big decimal that holds its data with an embedded array. Compressed big decimal is an absolute number based complex type based on big decimal in Java. This supports all the functionalities supported by Java Big Decimal. Java Big Decimal is not mutable in order to avoid big garbage collection issues. Compressed big decimal is needed to mutate the value in the accumulator. |

Druid doc builder
This website was created with Docusaurus.
To view documentation run:
npm install
Then run:
npm start
The current version of the web site appears in your browser. Edit pages with your favorite editor. Refresh the web page after each edit to review your changes.
Dependencies
- NodeJS. Use the version Docusaurus specifies, not a newer one. (For example, if 12.x is requested, don't install 16.x.) Docusaurus may require a version newer than that available in your Linux package repository, but older than the latest version. See this page to find the version required by Docusaurus.
- The Yarn dependency from Docusaurus is optional. (This Yarn is not the Hadoop resource manager, it is a package manager for Node.js).
- Docusaurus. Installed automatically
as part of the the above
npmcommands.
Variables
Documentation pages can refer to a number of special variables using the
{{var}} syntax:
DRUIDVERSION- the version of Druid in which the page appears. Allows creating links to files of the same version on GitHub.
The variables are not replaced when running the web site locally using the
start command above.
Spellcheck
Please run a spellcheck before issuing a pull request to avoid a build failure due to spelling issues. Run:
npm run link-lint
npm run spellcheck
If you introduce new (correctly spelled) project names or technical terms, add
them to the dictionary in the .spelling file in this directory. Also, terms
enclosed in backticks are not spell checked. Example: `symbolName`
