What happened?

Not really a bug, but maybe unexpected behavior. Since etcdctl del accepts an optional second parameter which deletes all keys in a range, these are very easy mistakes to make:

# Oh no, there was a space in the key I copied!
etcdctl del /registry/persistentvolumes/pvc-eef4ec4b-326d-47e6- f11c-6474a5fd4d89
# <deletes thousands of keys>

etcdctl put 'key s

After the content in parquet may be written by spark, the definition of bool is true or false. Regenerating the parquet file takes time, In tidb, bool behaves as tinyint, so proper type conversion will help improve the success rate of lightning import

The array overlap operator, &&, provides a convenient syntax for filtering for arrays that have one more more elements in common with another array. However, the && operator is not index accelerated, so an efficient inverted index scan in not planned. The current workaround is to rewrite the query by combining the containment operator with OR expressions:

Hi community,

This issue is for OpenForce

ReadwriteSplittingDataSourceRule.getWriteDataSource() need add unit test. I think should be consider DynamicReadwriteSplittingType and StaticReadwriteSplittingType.

Our CMake build process produces tarball packages using the cpack TGZ target. This produces a server and client package with a file layout meant to match where the various artifacts go.

Meanwhile, the packages we include on the download page are a flat archive of various binaries produced by the build process. This include one regular package and one debug package with debug symbols for a few

Description

Currently, the table "write_read_test" in keySpace "system_platform" is counted towards user tables, so even when the user has only one table, the portal shows the user has two tables.

Syntax for changing Iceberg table properties

ALTER TABLE an-iceberg-table SET PROPERTIES a-property-name = 'a-value'

Implementation tips

Implement the method io.trino.spi.connector.ConnectorMetadata#setTableProperties in io.trino.plugin.iceberg.IcebergMetadata.

Use org.apache.iceberg.BaseTable#updateProperties for updating table properties.

Test tips

Add

Use case:
Postgres compatible tools like Datagrip, DBeaver, etc. want to get (and sometimes set e.g. Azure Data Studio) the datestyle used by the database. It seems like there is already some implementation for that.

Feature description:
As a db tool engineer I want to be able to fetch the set datestyle of a database to be know how to interpret dates in my tool.

use Buffer instead of std::vector in column container

We may change the Buffer implementation in the future. but some function break this rules. we need fix it
eg:

raw::make_room(std::vector<T>* v, size_t n) -> raw::make_room(Buffer<T>* v, size_t n)

Currently we don't have any mechanism to limit the maximum number of clients that could be handled simultaneously.

This feature should be designed properly. Here is some clue: https://redis.io/topics/clients#maximum-number-of-clients

Now that we support more than 1 data type, we should include the values data type in cache nodes. This give us a way of easily identifying what type of data a key points to e.g. string, queue (and more types in the future)

Currently a cache node object consists of a Key, a Value and a TTL. We should also add a field specifying the type of the Value
