Syntax
FT.INFO <index-name>
Output from the FT.INFO page is an array of key value pairs as described in the following table:
| Key | Value type | Description |
|---|---|---|
| index_name | string | Name of the index |
| creation_timestamp | integer | Unix-style timestamp of creation time |
| key_type | string | HASH or JSON |
| key_prefixes | array of strings | Key prefixes for this index |
| fields | array of field information | Fields of this index |
| space_usage | integer | Memory bytes used by this index |
| fullext_space_usage | integer | Memory bytes used by non-vector fields |
| vector_space_usage | integer | Memory bytes used by vector fields |
| num_docs | integer | Number of keys currently contained in the index |
| num_indexed_vectors | integer | Number of vectors currently contained in the index |
| current_lag | integer | Recent delay of ingestion (milliSeconds) |
| backfill_status | string | One of: Completed, InProgres, Paused or Failed |
The following table describes the information for each field:
| Key | Value type | Description |
|---|---|---|
| identifier | string | name of field |
| field_name | string | Hash member name or JSON Path |
| type | string | one of: Numeric, Tag, Text or Vector |
