Enum MetadataStorageMode

java.lang.Object

java.lang.Enum<MetadataStorageMode>

dev.langchain4j.store.embedding.pgvector.MetadataStorageMode

All Implemented Interfaces:

Serializable, Comparable<MetadataStorageMode>

public enum MetadataStorageMode
extends Enum<MetadataStorageMode>

Metadata storage mode

• COLUMN_PER_KEY: for static metadata, when you know in advance the list of metadata
• COMBINED_JSON: For dynamic metadata, when you don't know the list of metadata that will be used.
• COMBINED_JSONB: Same as JSON, but stored in a binary way. Optimized for query on large dataset.

Default value: COMBINED_JSON
