What happened?

If you don't pass a --name argument to your etcd processes, they will all have the name default and the cluster will operate normally. However, when you add a member, the generated ETCD_INITIAL_CLUSTER variable will have multiple entries with the name "default". When this environment variable is used, etcd will parse these into a mapping under a single key ("defau

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:

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.

Need to migrate trino-maven-plugin to use GitHub actions instead of Travis CI. See trinodb/trino#6859 for some guidance.

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.

I thought the size of std::bitset<16> is 2 bytes, but it turns out it's 8 bytes

#include <bitset>
#include <iostram>

int main() {
    std::cout << sizeof(std::bitset<2>) << std::endl;
    std::cout << sizeof(std::bitset<8>) << std::endl;
    std::cout << sizeof(std::bitset<16>) << std::endl;
    std::cout << sizeof(std::bitset<32>) << std::endl;
    std::cout << sizeof(std::bitset

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
