  2. Dec 12, 2023rs-aggregate will aggregate an unsorted list of IP prefixes. Intended to be a drop-in replacement for aggregate6 with better performance. Takes a list of whitespace-separated IPs or IP networks and aggregates them to their minimal representation. Installation. rs-aggregate is built statically. CI-built binaries can be found in the GitHub ...
  3. Nov 13, 2024The sql_query_parser project provides a custom Rust parser for SQL-like queries, implemented using the Pest crate. It can parse SELECT statements with advanced query capabilities, including joins, conditional filtering, aggregate functions, grouping, ordering, and limiting the results. | Rust/Cargo package
  4. 6 days agoWhen aggregate or window feature is enabled (default), there are functions to compute combined hash over a set of values like a column in a table, e.g. sha256_concat and sha256_concat_hex. Just like scalar functions, multiple arguments are also supported, so you can compute a hash over a set of columns, e.g. sha256_concat(col1, col2, col3 ...
  5. Aggregate operators group and combine your data by 0 or more key fields. The same query can include multiple aggregates. The general syntax is: (operator [as renamed_column])+ [by key_col1, key_col2] In the simplest form, key fields refer to columns, but they can also be generalized expressions (see examples) Examples:
  6. May 7, 2024add Aggregate only, called once per row within a group. Perform needed calculations and save the data in the struct. remove Window functions only, called to remove a value from a group; It is quite possible, especially for simple functions, that there is no data that needs sharing. In this case, just make an empty struct and no allocation will ...

  8. Jan 24, 2025Shplonk, scheme #2 (aka private aggregation scheme from Halo Infinite, section 4) accumulates k opening tuples (Cf, z, v), each claiming that f(z) = v, commit(f) = Cf for a univariate polynomial f and points z, v, into a single one (C', z', v'), such that a proof for the aggregate claim attests that all other k claims are valid. It allows to ...
  9. Jan 26, 2025The [map_reduce()] function ends up evaluating the mapped function for each row and params, but extracts all join keys that, combined with the row and params, yields a non-trivial Aggregate. We thus extract, for each row and params , a branching function from join keys to Aggregate , and reduce ( merge :: Merge ) these branching functions ...

  11. 6 days agoElusion is a modern DataFrame / Data Engineering / Data Analysis library that combines the familiarity of DataFrame operations (like those in PySpark, Pandas, and Polars) with the power of SQL query building. It provides flexible query construction without enforcing strict operation ordering, enabling developers to write intuitive and maintainable data transformations. | Rust/Cargo package
