 * revisit line codec
-* add columns from schema on merge
-* Plugging JSON
-* replug examples
-* move datetime to quickwit common

 * reintroduce the gcd map.
 
 # Perf and Size
-* remove alloc in `ord_to_term`
 + multivaued range queries restrat frm the beginning all of the time.
 * re-add ZSTD compression for dictionaries
-no systematic monotonic mapping
-consider removing multilinear
-f32?
-adhoc solution for bool?
-add metrics helper for aggregate. sum(row_id)
-review inline absence/presence
-improv perf of select using PDEP
-compare with roaring bitmap/elias fano etc etc.
-SIMD range? (see blog post)
-Add alignment?
-Consider another codec to bridge the gap between few and 5k elements

 in benchmark, unify percent vs ratio, f32 vs f64.

 rename rank/select in unit tests
 Review the public API via cargo doc
 go through TODOs
-remove all  doc_id occurences -> row_id
-use the rank & select naming in unit tests branch.
 multi-linear -> blockwise
 linear codec -> simply a multiplication for the index column
-rename columnar to something more explicit, like column_dictionary or columnar_table
-rename fastfield -> column

 rationalization FastFieldValue, HasColumnType
-isolate u128_based and uniform naming
