FT.PROFILE

FT.PROFILE index SEARCH | AGGREGATE [LIMITED] QUERY query

Available in:

Redis Stack / Search 2.2.0

Time complexity:

O(N)

Apply FT.SEARCH or FT.AGGREGATE command to collect performance details

Examples

Required arguments

Note: To reduce the size of the output, use NOCONTENT or LIMIT 0 0 to reduce the reply results or LIMITED to not reply with details of reader iterators inside built-in unions such as fuzzy or prefix.

Return

FT.PROFILE returns an array reply, with the first array reply identical to the reply of FT.SEARCH and FT.AGGREGATE and a second array reply with information of time in milliseconds (ms) used to create the query and time and count of calls of iterators and result-processors.

Return value has an array with two elements:

• Results - The normal reply from RediSearch, similar to a cursor.
• Profile - The details in the profile are:
  • Total profile time - The total runtime of the query, in ms.
  • Parsing time - Parsing time of the query and parameters into an execution plan, in ms.
  • Pipeline creation time - Creation time of execution plan including iterators, result processors, and reducers creation, in ms.
  • Iterators profile - Index iterators information including their type, term, count, and time data. Inverted-index iterators have in addition the number of elements they contain. Hybrid vector iterators returning the top results from the vector index in batches, include the number of batches.
  • Result processors profile - Result processors chain with type, count, and time data.
