Can it be that after the scan it's just that enough time has
elapsed
so that all replicas are caught up? I'd say this is likely the
case.

Hi Petter
I'd like to clarify what exactly happened and exactly what are you
referring to as "inconsistency".
From what I understand of the first error you observed, the Kudu was
underprovisioned, memory wise, and the ingest jobs/queries failed. Is that
right? Since Kudu doesn't have atomic

Hi Mauricio
Andrew is right. That feature already exists in some form. With
READ_AT_SNAPSHOT you can provide a timestamp which will be the timepoint
under which all the scans are performed.
Note that, while generally supported and functionally tested, we haven't
focused a lot of resources
Hi
The acceptor thread only distributes work, it's very unlikely that is a
bottleneck. Same goes for the number of workers, since the number of
threads pulling data is defined by impala.
What is "extremely" slow in this case?
Some things to check:
It seems like this is scanning only 5

The suggestion of 20-30 per tablet is more about the number of available
cores than the size of the data.
Tools like impala derive parallelism from the number of tablets thus having
that count adjusted (but not necessarily equal to) to the core count gives
you a good performance tradeoff.
Of
cally as well using your code.

Hi Jason
memory_limit_hard_bytes refers to all the memory consumed by the tablet
server. It has an effect in many things but arguably the biggest effect is
that the tablet server will reject all writes when memory consumption
reaches this limit.
block_cache_capacity_mb dictates how much
Congrats Alexey and Will!!
