Seeking: efficient CL bitsets.

• data.int-map

  3 124 5.3 Java

  A map optimized for integer keys

  

The thing that spoils you about java is just the sheer momentum that it has enjoyed that CL never really had. There are a lot of different kinds of bit set / int set things you can find for java, for example. And the clojure data.int-map is a very nice piece of work that I have happily abused with a million keys to good effect, with nothing like it in CL.

• Primes

  45 2,363 7.0 C#

• InfluxDB

  www.influxdata.com featured

  Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.

  

• cl-intset

  1 4 10.0 Common Lisp

  A library for non-negative integer sets. It implements sets using bitsets.

A quicksearch turned up only cl-intset which is full of fun tricks using integers as bitsets, but isn't at all pragmatic if you're using large values.

• bit-smasher

  1 50 3.6 Common Lisp

  Common Lisp library for handling bit vectors, bit vector arithmetic, and type conversions.

Do you mean bit vectors? Common Lisp has them in the standard and https://github.com/thephoeron/bit-smasher is also useful for handling them.

• bit-ops

  1 9 10.0 Common Lisp

  Tools for writing optimized bit-vector routines

• RoaringBitmap

  24 3,390 8.5 Java

  A better compressed bitset in Java: used by Apache Spark, Netflix Atlas, Apache Pinot, Tablesaw, and many others

  

might be able to use one of the roaring bitmap implementations https://roaringbitmap.org/ via ffi, or port one to CL. been using them from clojure via java implementation, great lib.
