I need to implement some database hints (mysql keeps using wrong index).
Im using tastypie and django.
is there any hook to override to modify sql just before it is executed.
Is there any way to integrate hints with tastypie?

I am working on a project that involves me dynamically creating a database for each client. I could do this with PHP and MySQL, but for optimization, the project language is been changed to Go and PostgreSQL. So i am trying to see if there is a way to achieve this with go-pg or any method in Go.
I have a REST API around a PostgreSQL database, the API was built using the Django REST Framework (python). I have access to the PostgreSQL database and the API, but I'm not allowed to modify the django/python code.
My first approach is to make, kind of, an HTTP POST request via a trigger every time a new record is created in PostgreSQL. I found this but seems like it's not the best way to do what I need.
In the Neo4j side, I'm thinking of a periodic HTTP GET request to the API from within a cypher function, but does not exist such thing.
You should use the APOC procedures for integrating with other DBs via JDBC. PostgreSQL is supported.
You can also use APOC procedures like apoc.periodic.schedule or apoc.periodic.countdown to periodically execute a Cypher query in the background.
On the side of my Gooddata project, I maintain a small PostgreSQL database that contains a few tables.
I would like to be able to integrate both my ETL processes using the same tool, and it seems to me cloudconnect would be the easiest way, since I already have my whole GoodData ETL in it.
Here are the ways I tried to do it without success:
I tried to have a look in the documentation, and it seems to me that all the functionalities of CloverETL that enabled this (DBOutput, PostGreSQLDataWriter) are not available in Cloudconnect.
I managed to connect to the Agile Datawarehouse Service (Database attached to GoodData), but it seems that only the ADS database is able to understand the request:
COPY MyDataBaseTable (field1,field2) FROM LOCAL '${DATA_TMP_DIR}/CIforADS.csv'
even when I adapt the syntax to PostgreSQL because the dynamic addressing I use here does not seem to work.
Is there any way to proceed that I'm missing? Can anyone think of a workaround?
In general this could be achieved by using of "DBExecute" component, but
I'm not sure if I understand it well - do you want to load data into your own Postgres instance using CloudConnect?
I'm working on a project that keeps some access control information in the database. We're using that access control information to filter what the user can see. The filter that we're using is based on roles that the user has. We would like to use the Repository abstraction provided by Spring Data, but we would like to be able to adjust the generated queries before they are executed. Is there a way to attach a listener or an interceptor that will be called before a query is executed? That way we can get a reference to the query object and make whatever adjustments to the query we need to before the query is executed.
What we're thinking about doing is creating our own JpaRepositoryFactoryBean so we can override SimpleJpaRepository as described here. We would override SimpleJpaRepository.getQuery to make adjustments to the query. Then for all the generated finder methods we were thinking about extending PartTreeJpaQuery and overriding the PartTreeJpaQuery$QueryPreparer. In the QueryPreparer we would override QueryPreparer.createQuery methods. We weren't sure if that was the simplest way to get access to all queries before they get executed.
We thought about adding a org.springframework.data.repository.core.support.QueryCreationListener, but it would only get executed when the query is created. I think we need something more dynamic.
I'm not sure if you already know, but Spring Data team is working on that feature for the next release, to make it possible for Spring Security Team to add the support for ACLs then.
Add infrastructure for generic query augmentation
Spring Security issue that is blocked by the previous: Spring Security / Spring Data Acl Integration
In my company, we created a JpaRepositoryFactoryBean that would create a custom Repository to allow us to add the filter for the ACLs, but we just did that for the findAll and findOne methods, so we were loosing a lot of features of Spring Data and decided to revert that change and we're still thinking in a way to do it automatically. If we find out that it'll be too difficult, I think that we'll delegate that responsibility on the clients of the repositories and wait for the support for it in Spring Security/Data.
The original question already has 1 year. Did you find a clean way to do it?
Im in the start up phase of creating an internal system based on PHP and MongoDB. The users of this system are Javascript programmers and would like to be able to make custom queries to the Mongo database from a frontend gui with arbitrary Mongo shell queries. Of course this would not be a problem at all if I forced them to to write the queries with proper PHP arrays etc, but i would definitely like to avoid this.
I am not quite sure how to approach a feature like this without writing some advanced methods being able to restructure the queries to proper formated arrays that can be used in MongoClient PHP. One approach would be making use of the i.e. MongoDB::execute() method and run the javascript on the database server - a method i don't fancy at all.
Im kindly asking if you have any ideas on how to achieve the requested functionalities to some extend.
Thank you in advance.
