Apache Ignite: join between partitioned and replicated tables - ignite

Question

I'm evaluating Apache Ignite as a potential performance improvement in our setup.
I have two tables: one 22M records and the second 36k records. They need to be joined.
As the second table is relatively small I decided to keep it replicated across all nodes so the join could be executed locally on each node.
Here is my cache configuration:
<property name="cacheConfiguration">
<list>
<bean class="org.apache.ignite.configuration.CacheConfiguration">
<property name="name" value="metricsDailyCache"/>
<property name="groupName" value="group1"/>
<property name="cacheMode" value="PARTITIONED"/>
<property name="backups" value="0"/>
<property name="queryParallelism" value="1"/>
<!-- Other parameters -->
</bean>
<bean class="org.apache.ignite.configuration.CacheConfiguration">
<property name="name" value="privilegesCache"/>
<property name="groupName" value="group2"/>
<property name="cacheMode" value="REPLICATED"/>
<property name="backups" value="0"/>
</bean>
</list>
</property>
I have no persistence enabled.
So metricsDailyCache will store big table (22M) and privilegesCache will store small table (36k).
Tables DDL:
CREATE TABLE public.metrics_table (
id int PRIMARY key,
updated_at timestamp NULL,
period2 varchar NULL,
firm_id varchar NULL,
trader_id int NULL,
segment_name varchar NULL,
sector_name varchar NULL,
symbol varchar NULL,
measure_name varchar NULL,
measure_value float NULL,
market_average float NULL,
peer_average float NULL,
measure_rank int NULL,
measure_peer_rank int NULL
) WITH "CACHE_NAME=metricsDailyCache";
CREATE TABLE public.user_privileges (
id int PRIMARY KEY,
trader_id int NULL,
trader_name varchar NULL,
firm_id varchar NULL,
firm_name varchar NULL,
organization_profile varchar NULL,
tableau_user varchar NULL,
alias varchar NULL
) WITH "CACHE_NAME=privilegesCache";
Now, when I execute join:
with
user_privillages_distinct as (
select DISTINCT trader_id,
firm_id,
alias
from user_privileges
) SELECT DISTINCT sector_name
FROM metrics_table t
LEFT JOIN user_privillages_distinct u
ON t.trader_id = u.trader_id AND t.firm_id = u.firm_id;
it doesn't finish in a reasonable time (on Postgres it takes ~7s).
Is my understanding wrong?
Should I use partitioned cache for user_privileges and then define affinity key on join columns (firm_id, trader_id) instead?
