Create Elasticsearch mappings from Go structs
There is a small DSL for mapping Go types to Elasticsearch types. Like the json tags
found on structs, it is possible to provide custom behavior for Go struct fields.
To specify a custom data type, such as date for a uint64, put it right after the
es tag:
type MyStruct struct {
ts uint64 `es:"date"`
description string `es:"text"`
}Additional custom properties must be specified after the first item:
type MyStruct struct {
ts uint64 `es:"date,epoch_ms"`
description string `es:",indexignore"`
}| Property name | Description |
|---|---|
epoch_seconds |
Only to be used with a date data type, this specifies that the timestamp is in seconds. |
epoch_ms |
Similar to epoch_seconds, but with milliseconds instead. |
indexignore |
Tells Elasticsearch not to index (make searchable) this field. |
eager_global_ordinals |
Tells Elasticsearch to load ordinals eagerly rather than lazily (for search speed). |
To run tests:
go test .
