You'll find a short description in each module of what it does and how it relates to other modules.
|
2023-03-21 17:26:59 +01:00
|
|
|
The modules each have names like "library" or "process" or "feature". These have specific meanings.

|
|
|
|
|

### Processes
|
|
|
|
|
|
|
|
|
|
Processes are batch jobs that deal with data retrieval, processing and loading.

### Features
|
|
|
|
|
|
|
|
|
|
Features are relatively stand-alone components that serve some part of the domain. They aren't domain-independent,
|
|
|
|
|
but isolated.
|
|
|
|
|
|
|
|
|
|
* [features-search](features-search)
|
|
|
|
|
* [features-crawl](features-crawl)
|
2023-03-13 17:39:53 +01:00
|
|
|
* [features-convert](features-convert)
|
2023-03-12 10:50:31 +01:00
|
|
|
* [features-index](features-index)

### Libraries and primitives
|
2023-03-12 10:50:31 +01:00
|
|
|
|
|
|
|
|
Libraries are stand-alone code that is independent of the domain logic.
|
|
|
|
|
|
2023-03-07 17:32:16 +01:00
|
|
|
* [common](common/) elements for creating a service, a client etc.
|
|
|
|
|
* [libraries](libraries/) containing non-search specific code.
|
|
|
|
|
* * [array](libraries/array/) - large memory mapped area library
|
|
|
|
|
* * [btree](libraries/btree/) - static btree library
|
