The parser doesn't support materializing columns in Clickhouse CREATE TABLE statement
The MATERIALIZED keyword makes the column auto-computed and stored from an expression.
Sample query:
CREATE TABLE t (
url String,
domain String MATERIALIZED regexpExtract(url, '^(?:https?://)?([^/]+)', 1)
)
ENGINE = MergeTree()
ORDER BY tuple();
Error: ParseException: Encountered: <K_MATERIALIZED> / "MATERIALIZED", at line 3
