# Segment Overview
|
||
|
|
|
||
|
|
There are currently two types of Segments
|
||
|
|
1. Growing segment, dynamic insert is allowed, but can not load index for fast retrieving
|
||
|
|
2. Sealed segment, dynamic insert is disabled, loading vector index is supported
|
||
|
|
|
||
|
|
Both Segment types share the same interface, based on `SegmentInterface`, External callers only need to care about the behavior of the following interface as function declarations and corresponding constructor:
|
||
|
|
|
||
|
|
1. `SegmentInterface`
|
||
|
|
2. `SegmentGrowing` & `CreateGrowingSegment`
|
||
|
|
3. `SegmentSealed` & `CreateSealedSegment`
|
||
|
|
|
||
|
|
Other internal functions are hidden as implementation details in the following classes:
|
||
|
|
|
||
|
|
1. `SegmentInternalInterface`
|
||
|
|
2. `SegmentGrowingImpl`
|
||
|
|
3. `SegmentSealedImpl`
|
||
|
|
|
||
|
|
In principle, the reusable code logic of growing / sealed is written into the 'SegmentInternalInterface' as far as possible. The different parts of the two classes contain more different parts
|
||
