Delete retention policy for database with default true. What happens to the database retention policy in this case?

Store
1

step 1.

show retention policies on market

name duration shardGroupDuration replicaN default

autogen 0s 168h0m0s 1 false
exem_rp 672h0m0s 1h0m0s 1 true

step 2.

drop retention policy exem_rp on market
show retention policies on market

name duration shardGroupDuration replicaN default

autogen 0s 168h0m0s 1 false

step 3.

First, check that data is not retrieved (eg select * from tickers limit 3). I wonder what the retention policy during this time is.
