There is a document describing how to migrate an existing etcd cluster from HTTP communication to encrypted HTTPS.
The document uses v2-based CLI, some of those commands have different args or output format in their v3 equivalent, and some of them (like etcdctl cluster-health) doesn't seem to exist in v3. The documen

Description

The execution plan test in this file is written in code. Which has poor usability: It's hard to modify test result in code by hand.

Instead, we can move this test to file. Like what we did in other places. As the title said, this issue is focused on regenerating all the UTs in ./planner/core/cbo_test.go

Take what we did in planner/core/point_get_plan_test.go as

From MDN:

• Chrome has an "Intent to Deprecate and Remove the XSS Auditor"
• Firefox have not, and will not implement X-XSS-Protection
• Edge have [retired their X

Right now we have the following, which doesn't validatie the needs of a given view. This allows for any colors to be provided, not necessarily the ones that are required. I'd recommend making these color validations accurate, where for Gauge it would require the min and max for instance. I'm assuming these are required for gauge, that may be in error. Would be nice to provide swagger that p

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.

Describe the bug
When the elevated database user account does not have permission to create a schema, it cannot establish a connection with an existing database.

But when I provided the root account, I successfully established a connection with the database, but prisma created a schema called prisma.
Look like this:

Goals

Filter a List of primitives by @count using RealmSwift, since the docs suggest this is possible:

The aggregate expressions @count, @min, @max, @sum and @avg are supported on List and Results properties, e.g. realm.objects(Company.self).filter("employees.@count > 5") to find all companies with more than five employees.

Sometimes it is needed to store compressed data in the DB. Unfortunately not all the DBs have built-in compression and FUSE compressed FSes are not available for every OS. So it may make sense to store compressed binary blobs in the DB.

Unfortunately when one sees them in DBeaver he sees them compressed, but often they are needed uncompressed. So it'd be nice to have a feature to decompress the

Shall I assume that some of the performance issues with pouchdb-find come from the fact that it always include_docs? See here: https://github.com/pouchdb/pouchdb/blob/master/packages/node_modules/pouchdb-find/src/adapters/local/find/index.js#L87
Looks like there's no option to not include the docs and I can't grasp why including docs is necessary if indexes are created before calling find().

What you wanted to do

Users are confused about the "login" field that is related to ACL. Adding a way to inform Ratel that the ACL is disabled helps to hide it when necessary.

https://discuss.dgraph.io/t/ratel-unable-to-connect-dgraph-server-acl-user-password-error/6292

I searched the documentation, but I can't find any explanation of the "Write changes" and "Revert changes" buttons.

It's confusing for a new user that changes are not fully saved until you click "Write changes". The documentation should point this out and give a description of the underlying mechanism.

I still can't understand what is going on. Does the program issue a BEGIN or a SAVEPOINT

Your documentation shows no way to replace an objects value. Any updates to an object with:

db.get(name).find(selectors).assign(data).write()

merges the data with the existing object...not what I'd expect.

How can we replace a record without merging? Can you update your docs?

I've heard GUN mentioned multiple times, but I never understood what it is. This is my experience when looking at the website and navigating from it. Please take it as a constructive criticism of what seems to me as a promising software project.

I've navigated to the main website https://gun.eco/.
The page servers as more like a directory than a landing page.

The encryption section in Java docs https://realm.io/docs/java/latest/#encryption leads to an example that doesn't properly provide a best practice solution for how to store keys used for encryption.

Use multiple thread to load unconfigured schema meta data for different data sources to improve performance of loading.

The code is in RuleSchemaMetaDataLoader line 80, please search // TODO use multiple threads for different data sources

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

pgcli depends on humanize which is https://github.com/jmoiron/humanize.

The current version has a slightly odd behavior of rounding down unexpectedly:
