[~wadey], sorry for taking so long to get to this but I finally had some time
today. I agree with your assessment so far but unfortunately don’t have much to
add. It looks like CASSANDRA-12516 fixed what the cache was keyed on but not
all the {{getInterned}} call sites. Indeed the {{type}} column is the CQL
(value) type. Further, we no longer have the comparator after
{{LegacySchemaMigrator}} runs (of note, {{LegacySchemaMigrator}} does use
{{getInterned}} as intended but since we lose the comparator that only makes
things worse)*.
[~iamaleksey], do you have any thoughts on this since you reported the original
issue?

@iamaleksey thank you for the useful feedback. I did discuss this with
@krummas and I believe while there was a room for improvement, the thinking
back then was that the benefits would outweigh the cost. I looked through the
codebase and this was the best way to definitely verify range containment as I
was going for correctness. That said, what you suggest is obviously better. I
am concerned about scope creep in this PR. Would it be ok if we address it as
part of a separate PR?
It would also be useful, if we could design the effective range computation
and storage in the metadata. I am not sure what sort of gotchas I might run
into.

I mistakenly thought this index was a sampled index not a full index.
Requiring a comparison of every partition key in every sstable for the entire
data set seems like a big regression for some use cases.
I was trying and failing to find the reasoning for why we switched to this.

It's generally considered to be a bad practice to implement `equals()` and
`hashCode()` unless that class is stored in a set or a map - or an upstream
implementation of such. Otherwise it's just confusing boilerplate (confusing
because it implies that the class is used in ways it clearly isn't).
In this case, there is a `List` field in
`CassandraStreamHeader`, which has an `equals()`/`hashCode()` implementation,
which on the surface justifies these. But those, in turn, are actually dead
code. So what we should do is remove the implementations of `equals()` and
`hashCode()` here, and do the same in `CassandraStreamHeader`, being good
citizens.

As such it would be cleaner - and nicer to work with - to implement a class, say, `ComponentManifest` that would have an ordered map of `Component.Type` to `long` size, and expose the ordered keyset, with serializers for the whole manifest.

On a more general note, this is potentially quite an expensive thing to do,
especially for big sstables with skinny partitions, and in some cases this will
introduce a performance regression.
The whole optimisation is realistically only useful for bootrstrap, decom,
and rebuild, with LCS (which is still plenty useful and impactful and worth
having). But it wouldn't normally kick in for regular repairs because of the
full-cover requirement, and it won't normally kick in for STCS until
CASSANDRA-10540 (range aware compaction) is implemented. In those cases having
to read through the whole primary index is a perf regression that we shouldn't
allow to happen.
The easiest way to avoid it would be to store sstable's effective token
ranges in sstable metadata in relation to the node's ranges, making this check
essentially free. Otherwise we should probably disable complete sstable
streaming for STCS tables, at least until CASSANDRA-10540 is implemented. That
however wouldn't address the regression to regular streaming, so keeping ranges
in the metadata would be my preferred way to go.

Needs a change in ccm - [PR for ccm|https://github.com/riptano/ccm/pull/680].
Not sure which branch (master or cassandra-test) in the ccm repo is the "right"
one for PRs.
Updating line 3 in {{requirements.txt}} in dtests to {{-e
git+https://github.com/snazy/ccm.git@9608-jvm-options#egg=ccm}} fixes that as

[~KurtG] I believe the current state of the patch is to provide the options and
implement {{SimpleStrategy}}. We need CASSANDRA-14303 I believe to add support
for {{NetworkTopologyStrategy}}. I think for CASSANDRA-14303 the default would
only apply only if no datacenters were given in the declaration at all, e.g. {
{{'class': 'NetworkTopologyStrategy'}} } would be equivalent to { {{'class':
'NetworkTopologyStrategy', 'default_datacenter_replication': 3}} }. The adding
a datacenter flow is covered in CASSANDRA-14303 but briefly it relies on the
autoexpansion only to happen at {{CREATE}} or {{ALTER}} time. If you don't
supply {{default_datacenter_replication}} but do supply explicit datacenters
everything works the same as in the past, if you do supply it then any
datacenters that exist but are not specified in the {{CREATE/ALTER}} statement
get that default value added. The minimum validation catches e.g. { {{'class':
'NetworkTopologyStrategy', 'default_datacenter_replication': 1}} }
Removing a datacenter is slightly trickier because of the minimum rf validation
(to remove a datacenter in the presence of {{default_datacenter_replication}}
you have to provide an excluded datacenter with RF=0), but I think it will
still work because the validation happens after we template out the replication
map.

It has taken me some time (and @krummas's help) to prove that this wasn't a
correctness issue, but at its best this is confusing/misleading code.
We extract `sstableLevel` from the header, but don't use it anywhere.
Instead, since we stream `StatsMetadata` directly, we also inherit the level
from there - regardless of whether `CassandraOutgoingStream.keepSSTableLevel`
is set to `true`. If `LeveledManifest.canAddSSTable` check didn't exist, we'd
be in trouble here. For clarity, I would probably look at that flag, and
explicitly reset the level to `L0` if `keepSSTableLevel` is set to `false`.
P.S. What's the deal with all these `protected` fields?

Catching `RuntimeException` is really not the way we should be using

I agree. And thanks for your input here, [~benedict]. I appreciate having
another PoV on this subject.
[~snazy] I've been [running this branch on
circleci|https://circleci.com/gh/jasobrown/workflows/cassandra/tree/9608-circleci],
and the dtests have lot of failures (~120 or so). Can you take a look? Not
sure if it's an environmental problem or what (haven't had a chance to dig in
yet).

demand, but then must persist after it has been allocated.
bq. However, I feel like it's beyond the scope of this ticket
Agreed. Perhaps we should go with a simple solution and then file a separate
ticket to ensure no regression, as any of the approaches here will regress in
some way.
The best compromise of approaches here is probably the ReentrantLock approach,
as it is simplest and has the best behavioural profile, with the only cost
being a modest increase in heap for contended objects (which are typically
heavy already, else the chance of contention is low)
The other locking approaches are either more work and inferior to alternative
(wait or lock free) approaches we could invest the time in, or have worse
characteristics under contention (ie simple condition)

Jason Brown commented on CASSANDRA-9608:
[~benedict] Where do the Inflating Locks in your table come from? Are those
what you are thinking about when you earlier mentioned "a property using a
special inflated lock object, that can be used for synchronisation until there
is no contention, and the last owning thread sets the property to null on
completion." Or something else all together?

Everybody makes progress.
That is an interesting idea, and I'd be interested in hearing more (and/or
having a proposal/discussion on the dev@ ML). However, I feel like it's beyond
the scope of this ticket. Going to try to absorb your previous comment now (the
one with that table).

{quote}I was racking my brain to see if there's an alternative to allocating an
object on-demand
{quote}
Well, it would be possible to implement our own variant of the JDK's internal
locking, which has a shared pool of locks that are allocated to a given object
on demand, but this would have to be done in unsafe territory. This would be
quite possible too, but it's more involved. I would be happy to have a crack
at it, but that's probably several days' work instead of a couple of hours.
{quote}A {{ReentrantLock}} would need to be allocated and used
"pessimistically" up-front - i.e. for every instance of
{{AtomicBTreePartition}}, so some non-negligible overhead to what we have now.
{quote}
Why do you suppose this to be the case? It only needs to be allocated on
demand, but then must persist after it has been allocated. The current
proposals have the following characteristics (which are approximately true; I
haven't been absolutely thorough, particularly for ReentrantLock, and have
fudged some context-specific things):
||Operation||Simple Condition||ReentrantLock||Inflating Lock 1||Inflating Lock
2||
|Quiescent memory overhead
(after contention)|0 bytes|60 bytes|0 bytes|32-bytes|
|First Uncontended lock()|1x CAS
24-byte allocation|60-byte allocation|1x CAS
32-byte allocation (or 48-byte, depending on choices)|1x CAS
64-byte allocation (or 80-byte, depending on choices)|
|Future Uncontended lock()|1x CAS
24-byte allocation|1x CAS|1x CAS
32-byte allocation|1x CAS
32-byte allocation|
|First Contended lock()|2x CAS
112-byte allocation|3x CAS
32-byte allocation|1x CAS
32-byte allocation|1x CAS
32-byte allocation|
|Future Contended lock()|1.5x CAS (only hop tail once per two additions)
64-byte allocation|3x CAS
32-byte allocation|1x CAS
32-byte allocation|1x CAS
32-byte allocation|
|Release|2x volatile write
1x volatile write + 1x unpark *_per_* waiting thread
_If > 1 waiting thread: *will incur all*_
_*contended lock() costs again*_|2x volatile write
1x CAS + 1x unpark *_if_* waiting thread|1x volatile write
1x volatile write + 1x unpark *_if_* waiting thread
1x CAS if no waiting threads (to deallocate safely)|1x volatile write
1x volatile write + 1x unpark *_if_* waiting thread|
There are other possible variants with different tradeoffs, for instance
reducing allocation costs for uncontended lock() in option (2) at possible
modest increase in CPU and implementation complexity. Again, I disclaim any
modest inaccuracies as didn't want to spend too long putting this together.

Was going to close this but realised it's possibly still actually a bug in
Cassandra.
[~arokhin] do you have an example schema and query string that causes this?
Also what plugin you are using if that applies?

Robert Stupp commented on CASSANDRA-9608:
-
{quote}I assume this is to handle e.g. the removal of
Unsafe.monitorEnter/monitorExit?
{quote}
Right.
{quote}could go with the {{volatile ReentrantLock}}
{quote}
A {{ReentrantLock}} would need to be allocated and used "pessimistically"
up-front - i.e. for every instance of {{AtomicBTreePartition}}, so some
non-negligible overhead to what we have now.
We could, as [~benedict] proposed, use some "special" handling and gave it [a
try in this
commit|https://github.com/snazy/cassandra/commit/41ea5eb96c95d7896b452df7ae228ecccd95c660].
Haven't tested it though, but it's based on {{SimpleCondition}} instead of
{{Lock}}, because that one is a) already in the code base and b) doesn't
require an explicit {{lock()}}, and therefore prevents the "pessimistic"
allocation and use in every case.

Unsafe.monitorEnter/monitorExit?
{quote}
Ahh, sorry for the lack of context, [~benedict], but yes, you've hit the nail
on the head.
I was racking my brain to see if there's an alternative to allocating an object
on-demand, which of course requires contending on assignment to a share field
in the {{AtomibBTreePartitionBase}}, and then contend on the allocated object.
(Which is what {{Unsafe.monitorEnter()}} gave us a way around). I see we're not
gonna be that lucky.
bq. Or we could implement some static helper methods to help us lock against a
property using a special inflated lock object, that can be used for
synchronisation until there is no contention, and the last owning thread sets
the property to null on completion
I'd be interested in a sample of this as, tbqh, I don't understand what you are
proposing here - but I don't want you invest a lot of time just for my
edification. I suspect, at a minimum, we could go with the {{volatile
ReentrantLock}} for now, but could consider [~benedict]'s idea if it's
reasonable (and doesn't burden him too much). wdyt, [~snazy]?
