Why resource_group_id is varchar type in exact_match_source_selectors?

[byungnam]

Hi. I have a question about a table named exact_match_source_selectors.

There is a column named resource_group_id, which has bigint type for every table but except from exact_match_source_selectors. It has varchar type on there.

Why is that? Even the committer wrote "WTF" from the comment.

presto-gateway/gateway-ha/src/main/resources/gateway-ha-persistence.sql

Lines 67 to 68 in 3d3159e

	CREATE TABLE IF NOT EXISTS exact_match_source_selectors (
	resource_group_id VARCHAR(256) NOT NULL, -- WTF varchar?!

Is it intended? If so, what was the reason to do that?

Any update on this the script does not work in its current state. This is the update I had to make to the script to run.

CREATE TABLE IF NOT EXISTS exact_match_source_selectors (
    resource_group_id VARCHAR(128) NOT NULL,  -- WTF varchar?!
    update_time DATETIME NOT NULL,

    -- Selector fields which must exactly match a query
    source VARCHAR(256) NOT NULL, -- (reduced from 512)
    environment VARCHAR(128),
    query_type VARCHAR(128), -- (reduced from 512)

    PRIMARY KEY (environment, source, query_type),
    UNIQUE (source, environment, query_type, resource_group_id)
);
