Integration with embedding library
Proposal: We should add parsing of the parameters to enable connection with the new library for automatic embeddings. Currently, I suggest starting with the following specification: fields = "field1, field2" : fields we should use as the source for text …

to_string(a) requires a to be in the select list
to_string(<bool>) works only if the <bool> is in the select list too, otherwise it returns an empty value: mysql> drop table if exists t; create table t(a bool) engine='columnar'; insert into t(id, a) values(1, 1); select to_string(a) from t; select a, to …

Add lz4 compression to strings
Currently strings are stored basically uncompressed (only lengths are compressed) when table compression is not applicable. It makes sense to try to add LZ4 compression to such strings to save disk space (string hases used for grouping and filters are …

Improve filtering performance by using SIMD predication
When columnar storage processes a filter, there are two heavy stages - unpacking data and processing the filter. Filtering performance can be improved by replacing conditions like if ( ( i==(ACCESSOR_VALUES)m_tValue ) ^ (!EQ) ) with predication using _ …
