Yes. As described here https://speedment.github.io/speedment-doc/crud.html#create-with-persist you can apply the
persister() to a stream of entities. For example, myFilmList.forEach(films.persister())). If performance is important, do the updates in a transaction as described here https://speedment.github.io/speedment-doc/crud.html#transactions
Is there any operation for truncate the whole table in the Database..Because in the document it is saying like only remove some rows based on the condition. @minborg
You can remove all rows in a table by streaming in a transaction as described https://speedment.github.io/speedment-doc/crud.html#transactions If performance is important, it is probably best to do this via SQL (e.g. DELETE FROM sometable)
There is no specific way of trunkating a table i Speedment.
We can also done by using filter,But for applying filter it takes whole data from DB. That's why is there any option like that......
Yes you can! There is a predicate called
in() that is perfect for that. See https://speedment.github.io/speedment-doc/predicate.html#in
.filter(Film.ID.in(myIdSet)) for example.
Put the id:s in a
Set rather than in a List
(you can use a List if you want, bus Set gives better performance)
or otherwise it will take only that particular records from db?
So it will only take those particular records from the db.
You can see exactly what is sent to the database by adding
.withLogging(LogType.STREAM) to your application bulder.
I am having a list of data and the size of the list is 100000.
using the persist we have to store one by one data,is there any operation to perform whole list insert to db at same time?
Use transactions to speed up the inserts as described here: https://speedment.github.io/speedment-doc/crud.html#transactions
@vishnu2497 There is a project called MapStruct that you can use for mapping between different entities. https://github.com/mapstruct/mapstruct
Thanks @minborg for suggesting MapStruct.I am having a question that i have 200000 records and using transaction/Persist it stores 1000 records/second.If is there any better way to increase the speed of storing or otherwise is there any better way to use transaction effectively to increase the data storing into Db?
Each thread has its own transaction.
Hi, I would like to "register" for a free licence with my company email address. But I can't, the registration page doesn't accept my email address "gbuyle@cibg.brussels".
Could you adapte the registration page.

Hi, I was reading one of your articles at DZone, about imperative style vs. declarative style and Speedment was mentioned. I was curious to known what is Speedment and if it is a valid replacement for Hibernate. I am convinced and I would like to present it at our company as part of knowledge sharing.Hopefully I can convinced my company (development department) to use it in further development projects.
Hi @gbuyle, we currently don't provide the manual in its entirety as a PDF. Although I found a very effective plugin for Chrome that can render individual chapters to PDF in a very simple manner. I've described how it's done here: https://speedment.github.io/speedment-doc/index.html#pdf-rendering-of-the-documentation
is it possible to connect Speedment with Cassandra DB?
