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

Please consider adding a way to control which nodes participate in an IMPORT operation so that nodes in far regions can be excluded from the import.

Consider a 3-region cluster, with nodes in: [Japan, US West, EU]. And let's import a table into a database that has only a primary region defined in US West. All of the table's replicas will be located in US West. And the CSV data to be imported is

    @Test
    public void assertMethod() {
        assertThat(h2Repository.getType(), is("H2"));
        assertSetProperty();
        assertPersistAndGet();
        assertPersistAndGetChildrenKeys();
        assertDelete();
        h2Repository.close();
    }

Splitting assertMethod() method.

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

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

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" [

Refactoring request

The following two APIs need to pass tablet_id and schema_hash, while these two parameters already exist in tablet_meta or meta_pb, so there is no need to pass them again.

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
