Thanks Eric! Yes, the data block cache is already enabled. From the table config, I see:
default | table.cache.block.enable .................. | false site | @override .............................. | true Actually, there is no ingestion task running at that time when I ran the tests (which only do read). What is other possibility? Looking at the total tablets and total entries being queried from the Monitor UI, they are not like big number, so I have some doubt that 16GB data cache is not enough space, but I could be wrong.
