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

Status Server API for ListSession suggests that a session can have more than one active queries.

According to @itsbilal , this stems from back in the days where we allowed for parallel query execution. This has since been removed. We should clean up the API payload.

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

source: https://docs.yugabyte.com/latest/architecture/transactions/isolation-levels/#root

We begin the section by listing out 4 transaction isolation levels in decreasing order of strictness. Where possible, subsequent sections should follow this order to make it easier for readers to follow. For example, rewrite the second paragraph to read:

YugabyteDB supports three transa

Instead of creating on the fly an Iceberg table with Trino and run queries against it, use static resources for setting up an Iceberg test environment which can be used to read Iceberg v1 / v2 tables and guard trino-iceberg plugin against regresssions.

Use case:
Concatenate TEXT or to TEXT castable type values using a given separator, for example concatenate address parts by comma.

SELECT concat_ws(',', '535 Mission St.', '14th floor', 'San Francisco', 'CA', '94105') AS address;
--> 535 Mission St., 14th floor, San Francisco, CA 94105

Feature description:
Add support for the `concat_ws ( sep text, val1 "any" [

Enhancement

Currently, for a clone task, the client first gets a list of files, then for each file, get file length first then download the file, this can be optimized, when getting file list, also add file length information, so we don't need to get file length later.

Users will expect the current SQL to fail if they're using unimplemented features, not the whole compute node or frontend to panic. We should avoid using unimplemented! macro in production code and replace them with ErrorCode::NotImplemented.
