Works with tables in the MergeTree family. force_index_by_date ĭisables query execution if the index can’t be used by date. Used when performing SELECT from a distributed table that points to replicated tables.īy default, 1 (enabled). See Replication.ĬlickHouse selects the most relevant from the outdated replicas of the table. fallback_to_stale_replicas_for_distributed_queries įorces a query to an out-of-date replica if updated data is not available. If enable_optimize_predicate_expression = 0, then the execution time of the second query is much longer because the WHERE clause applies to all the data after the subquery finishes. If enable_optimize_predicate_expression = 1, then the execution time of these queries is equal because ClickHouse applies WHERE to the subquery when processing it.

SELECT count() FROM (SELECT * FROM test_table) WHERE date = ''.

SELECT count() FROM test_table WHERE date = ''.

Predicate pushdown may significantly reduce network traffic for distributed queries. Turns on predicate pushdown in SELECT queries.

Distributed subqueries for more information on how to use GLOBAL IN/ GLOBAL JOIN.

This setting helps to reduce the number of calls to external sources while joining such tables: only one call per query. We need to scatter their data on the fly during distributed processing with the GLOBAL keyword - GLOBAL IN/ GLOBAL JOIN.Īnother use case of prefer_global_in_and_join is accessing tables created by external engines. Here is when the prefer_global_in_and_join setting comes into play.įor example, we have query serving nodes that contain local tables, which are not suitable for distribution. IN/ JOIN operators are replaced with GLOBAL IN/ GLOBAL JOIN.Īlthough SET distributed_product_mode=global can change the queries behavior for the distributed tables, it's not suitable for local tables or tables from external resources. IN/ JOIN operators are not replaced with GLOBAL IN/ GLOBAL JOIN.

allow - Allows the use of these types of subqueries.Įnables the replacement of IN/ JOIN operators with GLOBAL IN/ GLOBAL JOIN.

global - Replaces the IN/ JOIN query with GLOBAL IN/ GLOBAL JOIN.

local - Replaces the database and table in the subquery with local ones for the destination server (shard), leaving the normal IN/ JOIN.

Prohibits using these types of subqueries (returns the “Double-distributed in/JOIN subqueries is denied” exception).

Not used for a table-valued remote function.

If the subquery concerns a distributed table containing more than one shard.

Only if the FROM section uses a distributed table containing more than one shard.

Only applied for IN and JOIN subqueries.

If anyone has any idea why this might be happening it would be appreciated.Changes the behaviour of distributed subqueries.ĬlickHouse applies this setting when the query contains the product of distributed tables, i.e. when the query for a distributed table contains a non-GLOBAL subquery for the distributed table. We connect via a secure gateway in our DMZ configured in SSL Gateway mode. RAS Server version is 16.2 19429 on Server 2008 R2. I have tried the latest client v2 (64-bit) but it has the same issue. I then configure the connection again in the client and all works well again (for a while). The only way I have found to get around the problem is to delete the following folder: I have not seen this happen on computers where users each have their own local profile however this isn't a practical model for us at the moment in our retail stores. Other users connecting to the same server/applications do not experience the same problem at the same time.

The username and password are clearly correct as I get the list of applications. I've tried to log in myself with known good credentials and experience the same problem. On investigation I have found that the client will accept the user's username and password and present them with the list of published applications but when the try to run one of the applications or published desktop they get an error " - The username and password is incorrect.". After some time, we get called by our users reporting that they can't log on.

After the client is installed and configured it works fine for a while. We are having a problem that keeps recurring. The Parallels RAS client policy is set to not remember passwords.
