+ * + *

+ * Key features and use cases: + *

+ *
    + *
  • Index abstraction: Applications can use stable alias names while underlying indexes change

  • Blue-green deployments: Switch traffic between old and new indexes seamlessly

+ * + *

+ * Key features and use cases: + *

+ *
    + *
  • Atomic updates: Change alias target without downtime
    • + *
  • Index migration: Seamlessly switch from old to new index versions
    • + *

    • + *
  • Performance options: TIMEOUT, SLOP, INORDER

Performance Considerations:

    + *
  • LOAD: Load specific document attributes for processing

  • GROUPBY: Group results by one or more properties
    • + *
  • REDUCE: Apply reduction functions (COUNT, SUM, AVG, MIN, MAX, etc.)

    • + *
  • LIMIT: Paginate results efficiently

Performance Considerations:

+ * FT.AGGREGATE runs a search query on an index and performs aggregate transformations on the results. It provides a powerful + * aggregation pipeline that can group, sort, apply mathematical expressions, filter, and limit results in a single command. + *

+ * + *

Basic Usage:

+ * + * 
+ * 
+ * {
+ *     @code
+ *     // Simple aggregation with grouping and counting
+ *     AggregateArgs args = AggregateArgs. builder().groupBy("category")
+ *             .reduce(Reducer.count().as("count")).sortBy("count", SortDirection.DESC).build();
+ *     SearchReply result = redis.ftAggregate("myindex", "*", args);
+ * }
+ *
+ * + * + *

Advanced Pipeline Example:

+ * + * 
+ * 
+ * {
+ *     @code
+ *     // Complex aggregation pipeline
+ *     AggregateArgs args = AggregateArgs. builder().load("price", "quantity", "category")
+ *             .apply("@price * @quantity", "total_value").filter("@total_value > 100").groupBy("category")
+ *             .reduce(Reducer.sum("@total_value").as("category_total")).reduce(Reducer.avg("@price").as("avg_price"))
+ *             .sortBy("category_total", SortDirection.DESC).limit(0, 10).dialect(QueryDialects.DIALECT2).build();
+ * }
+ *
+ * + *

Supported Operations:

+ *
    + *
  • LOAD - Load document attributes from source documents
    • + *
  • GROUPBY - Group results by one or more properties with reducers
    • + *
  • SORTBY - Sort results by properties with ASC/DESC directions
    • + *
  • APPLY - Apply mathematical expressions to create computed fields
    • + *
  • FILTER - Filter results using predicate expressions
    • + *
  • LIMIT - Limit and paginate results
    • + *
  • WITHCURSOR - Use cursor-based pagination for large result sets
    • + *
+ * + *

Performance Considerations:

+ *
    + *
  • Attributes used in GROUPBY and SORTBY should be stored as SORTABLE for optimal performance
    • + *
  • LOAD operations can hurt performance as they require HMGET operations on each record
    • + *
  • Use SORTBY with MAX for efficient top-N queries
    • + *
  • Consider using WITHCURSOR for large result sets to avoid memory issues

Available Reducer Functions:

  • AVG - Calculate the average of numeric values

  • MAX - Find the maximum value

  • COUNT_DISTINCT - Count unique values of a field

+ * + *

+ * This basic variant uses default aggregation behavior without additional pipeline operations. For advanced aggregations + * with grouping, sorting, filtering, and custom transformations, use [ftAggregate(Any, Any, AggregateArgs)]. + *

  • REDUCE: Apply reduction functions (COUNT, SUM, AVG, MIN, MAX, etc.)

Performance Considerations:
