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.

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.
There are several software projects (e. g. libneo4j-client) that implement the only documented version of the Bolt protocol, version 1.
Neo4j 4 drops support for Bolt version 1 with neo4j/neo4j@9ff0780. As a consequence, Neo4j 4 no longer supports the only version

使用的elastic-job版本:2.1.1。
我的一个定时任务为通过 http 方式(使用 OKHttp 发送 http 请求)执行某个方法(例如:http://ip:port/myapp/synFundData)。
当调用上述接口时如果服务器返回504(后台执行时间太长导致超时),请问该定时任务是否会自动重试?因为我从 Nginx 的日志中发现:每隔30秒Nginx 会收到一个同样的http请求,且返回的状态码都是 504,日志如下:
...remote_user=- [16/Nov/2017:08:40:01 +0800] request="GET /xxx/synFundData HTTP/1.1" status=504
...remote_user=- [16/Nov/2017:08:40:31 +0800] request="GET /xxx/synFun

Use case:
Have better compatibility with PostgreSQL tools
Feature description:
PostgreSQL supports various Data Type Formatting Functions
CrateDB has date_format and format as alternative, but for improved tooling support it would be good to have the PostgreSQL variants:
- `to_char(timestamp, text
According to documentation, BUILTIN_ALIAS_OVERRIDE was designed to replace datetime functions in unit tests. This implementation has many disadvantages.
-
There are 5 standard and many non-standard functions, they may get out of sync with such replacements.
-
There are other places where current timestamp is used, for example, some conversions between datetime values use current timestam

Although, the example described in that tutorial covers usage of basic Enums which is now best handled by the dedicated Enum-plugin. Custom TypeMappers are still needed in some case though, hence this tutorial should be updated to cover a more relevant use ca

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
