Database

A database is a structured set of data held in a computer, most often a server. Databases use a database management system (DBMS) that interacts with users, similar to a lookup table. Modern databases are designed to allow for creation, querying, updating, and administration of the data it holds.

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.

Feature Request

Is your feature request related to a problem? Please describe:

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

const XLSX = require('xlsx');

const wb = XLSX.utils.book_new();

const ws = XLSX.utils.json_to_sheet([]);

XLSX.utils.book_append_sheet(wb, ws, 'Bug sheet');

ws.A1 = { t: 's', f: 'square' };

XLSX.writeFile(wb, 'formula.ods');

The resulting .ODS file contains:

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

Describe the bug
Any attempt to test a subscription directly to the Prisma server via Playground returns the following error:

The provided query doesn't include any known model name. Please check for the latest subscriptions API.

In review of the WS transactions in the browser console, I can see I am receiving this response from the Prisma endpoint, but nothing is being logged by Pri

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

Experience Report

I am currently ingesting a large continuous streaming data set. The most recent data is the most important data. The oldest - either by policy or by least importance needs to be aged-off. Today, we use Neo4J Community Edition. We perform a query to find nodes/relationships older than a specific date and then delete them.

Note: Feature requests are judged based on user

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?

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

The test is giving following error when trying to generate SELECT query from the LINQ.
