Use it with an existing project to process orders from MySQL database ?

[KabDeveloper]

Hi,

I have a custom MySQL database structure, is there a way to adapte your awesome work to match my database ?

If yes, approximativally what is the expected processing performance per second ?

Thank you

[Justin Wilson]

You should follow up with the new maintainer.

@enewhuis Hi ! Is there a way to combine your work using a REDIS database or MySQL ?

First of all, what database are you using to store orderbook ?

Thank you

[Eric]

You need to think of the order book like you would Redis. For maximum performance the order book _is_ the database. What you might consider is to stream trades and quotes from the order book and capture them into some other storage. For playing orders into Liquibook you'd want to write a small loader function. Keep in mind that this library is a pure C++ header library and, as such, is a code library and not software as a service, per se.

@enewhuis Thank you for your answer ! Really appreciated.

Since my level on C++ is limited, can you give some infos (Not a code or doing the work) but only hint on how it's possible to process it and make it using REDIS for example ? In other words, how to make it fetching orderbook from a REDIS database (I want just to identify the part of the code responsible to get the order book in order to launch the matching algo - Only nothing else).

Meanwhile, from where your code fetching the orderbook ? is it using a database or i am misunderstanding your answer ... sorry if so.

Thank you in advance for your time.

@bcashier the C++ library maintains the order book in the local memory of the process that instantiates and runs the C++ templated classes. This is a build-your-own solution. Any loading from an external database would have to be done by hand by writing additional C++ code that interfaces to the database.

I am closing this issue since it is more of a confirmation of library intent rather than an actual issue/problem with Liquibook. Feel free to repost if you'd like more discussion.
