-----------------------------------------
Summary: Sql. Wait for system views to complete registration on
node start/join
Key: IGNITE-24703
URL: https://issues.apache.org/jira/browse/IGNITE-24703
Project: Ignite
Issue Type: Improvement
Components: sql
Reporter: Pavel Pereslegin
Currently, when a node starts, we do not wait for the completion of catalog
command which creates/replaces system views.
See {{SystemViewManagerImpl}}
{code:Java}
public CompletableFuture<Void> completeRegistration
{code}
Initially, we waited for this future to complete at the node start, but this
noteceably increased the test execution time (by about 10%). And at that moment
we decided to remove this delay.
As a result, any integration test that accesses system views is now forced to
wait this future separately.
{code:java}
@BeforeAll
protected void awaitSystemViewRegistration() {
await(systemViewManager().completeRegistration());
}
{code}
It is necessary to repeat the attempt to add a wait when starting (or joining)
a node and check whether there is a slowdown in the execution of integration
tests. If it is insignificant, then leave this condition when starting the node
and remove it from the tests.
