I'm using TLS on etcd 3.3.12 and have a mix of etcd proxies and masters. The proxies don't seem to honour the --cipher-suites setting, as it ends up with ECDHE-RSA-AES256-GCM-SHA384 despite --cipher-suites=TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305,TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256 being set.

This is a really minor nit, but the EXPLAIN output on binary strings is different from what I expected:

CREATE TABLE t1 (
 id INT NOT NULL PRIMARY KEY auto_increment,
 b varchar(255) not null,
 c varbinary(255) not null,
 index (b),
 index (c)
);


INSERT INTO t1 (b,c) VALUES ('a', 'a'),('b

In PostgreSQL, @ is a unary operator that returns the absolute value of a number. For example:

jordan=# select @ -5.0;
 ?column?
----------
      5.0
(1 row)

CockroachDB is missing such a unary operator.

Throw NullPointException when INSERT column and values mismatch.
It is better to throw suitable SQLException for JDBC-driver and proxy.

The tasks are:

• Throw suitable SQLException for JDBC-driver.
• Report suitable error packet with MySQL proxy.
• Report suitable error packet with PostgreSQL proxy.

With the new issue reporting mechanism in place (PR #2605), the old TraceEvent cache based implementation specifically for trace file open failure can be removed.

On a sharded collection, if you try to create a custom index (e.g. hash index) with uniqueness, that doesn't include the sharding key (which by default is the autogenerated _key) then it will fail with an error like:

Index creation failed: shard key '_key' must be present in unique index

There's zero documentation that I could find around this, and it's fairly fundamental, since you can't

Hello Philip!
I think there is an issue with this part of the code of rqlite (store/store.go).

func (s *Store) Database(leader bool) ([]byte, error) {
	if leader && s.raft.State() != raft.Leader {
		return nil, ErrNotLeader
	}
	// Ensure only one snapshot can take place at once, and block all queries.
	s.mu.Lock()
	defer s.mu.Unlock()

	f, err := ioutil.TempFile("", "rqlilte-snap-

The beginning of the course is pretty boring, and there's not a lot of interesting background reading before project 1. I'm thinking a great way to start it off would be to make the first reading a link to a powerfully inspiring experience report. Something that makes people psyched to learn how to write systems programs in this unique language.

Here are two I've been suggested but haven't eval

The steps described in our README does not work for me: https://github.com/citusdata/citus/blob/master/CONTRIBUTING.md#following-our-coding-conventions

The main problem is that after cloning the tools repo we need to run make install from top level instead of uncrustify because many of the variables are defined at the top level.

Existing test actions that can be used here. We would want to test only the yugabyte and yugaware helm charts and not all the charts in this repo.

(e.g - macOS):

1. Create a section with installation steps:

• brew install cmake autoconf libtool gcc automake openssl
• export PKG_CONFIG_PATH="/usr/local/opt/openssl/lib/pkgconfig"

2. Update README.MD
3. Update build.sh(force linking openssl doesn't work anymore)

I've wasted a lot of time trying to resolve openssl dependency issue, by applying solutions which are not relevant any

large-size-value writes will lead to the instability of Pegasus. We encounter many cases where the client continuously wrote >=1MB value (though in quite low qps) which caused high tail latency of other tables, even caused the program somehow coredump.

We need to implement integration/unit tests for internal/transport package.

In the last section of the tutorial, it goes:

Directly using this setup incurs an error when launching the app,
causing the server unable to deserialize the corfumsg, such as follows:
