Always to test tidb performance by POC,sometimes we will use the production data,sometimes we can use public dataset such as ONTIME,like percona. the Genaral data format is CSV,could you provide an example like Percona-lab which used for TiDB.

See example below. Best plan is a lookup join, but we don't get that with the semi-join. The reason is that each side is projecting a tuple, and we are constraining those to be equal. A rule that detects this projection and converts to multiple equalities should fix this.

  a INT,
  b INT,
  PRIMARY KEY (a,b)

A command line option could be implemented to make this configurable

The documentation here:
https://github.com/StackExchange/Dapper/tree/master/Dapper.Contrib#special-attributes

Says "[Table("Tablename")] - use another table name instead of the name of the class"

But that is not correct, the code here:
https://github.com/StackExchange/Dapper/blob/master/Dapper.Contrib/SqlMapperExtensions.cs#L309

takes the class name and add's an "s".

So it seems to

Sometimes it is needed to store compressed data in the DB. Unfortunately not all the DBs have built-in compression and FUSE compressed FSes are not available for every OS. So it may make sense to store compressed binary blobs in the DB.

Unfortunately when one sees them in DBeaver he sees them compressed, but often they are needed uncompressed. So it'd be nice to have a feature to decompress the

The first time that a request is being made, it works fine but after the timeout, it won't all

TupleDomainFilters for IN predicates are optimized to use hash tables for lookups and offer O(1) performance, but NOT IN filters are not optimized and give O(n) performance. Yet, there is no reason why IN predicate optimization couldn't apply to NOT IN. We could extend BytesValues and BigintValues to add a flag indicating that this is a NOT filter and add logic to com.facebook.presto.orc.TupleDoma

We have a simple MergeTree table with ~1M records. Sometimes we need to get last 10 records ordered by id, but we’d also like to get the total number of rows returned by the query if there were no limit.

Is the README the only documentation available for this project? I find myself having to read the source to understand the interface and features that are available (e.g., context managers, bulk_query, etc.).

In the case of bulk_query, the arguments are simply passed through to the underlying SQLAlchemy engine, with no explanation. I tracked it down in [SQLAlchemy's documentation](https:/

It looks like a great tool, is it possible to translate the documentation to English?

1. has_children

We already have most of our Directus API 2.x endpoints/params within Paw for testing. We could finish adding all of these and then potentially use their code generators to create SDKs for our secondary languages.

We also have a Swagger file for 98% of API 1.1 — so we could update that (and make sure that OpenAPI allows for our filteri

I think there is an issue with this part of the code of rqlite (store/store.go).

Which version and edition of Flyway are you using?

5.0.7

Which client are you using? (Command-line, Java API, Maven plugin, Gradle plugin)

Java with Hibernate

The linked Stackoverflow entry is only for Hibernate 4.x
I found this way to include Flyway with Hibernate 5.x for example in Wildfly >= 10
Perhaps it is worth for documentation:

After facing an issue caused by Ransack interpreting 1/'t' as true and some unsuccessful research, I found about the sanitize args and the recommended way to skip them. The documentation never mentions that ransackable_scopes_sanitize_args must be a class method and the example shown defines an instance method.

I think that's worth a documentation update, making more clear how to use th

Steps to reproduce the problem:
I wanted to show how much money remaining for free shipment. I couldn't find a widget inside the OrderSummary/default.cshtml before the

It is good to have a widget there so we can add any warning message there

Steps to reproduce

go to : http://orientdb.com/docs/3.0.x/orientjs/OrientJS.html
find the link for API Docs
click it.

Since we are working on #732 and adding a Concurrent.Futures backend we should add documentation on how to use it.

Tasks:

• Update Android Documenation!
• May be add a build issue FAQ, for example #2543
