MapDB VS Chronicle Map

Compare MapDB vs Chronicle Map and see what are their differences.

MapDB

MapDB provides concurrent Maps, Sets and Queues backed by disk storage or off-heap-memory. It is a fast and easy to use embedded Java database engine. (by jankotek)

Chronicle Map

Replicate your Key Value Store across your network, with consistency, persistance and performance. (by OpenHFT)

  • GC, hands off my data!
    6 projects | dev.to | 27 Oct 2023
    I decided to start with an overview of what open-source options are currently available. When it comes to the implementation of the on-heap cache mechanism, the options are numerous – there is well known: guava, ehcache, caffeine and many other solutions. However, when I began researching cache mechanisms offering the possibility of storing data outside GC control, I found out that there are very few solutions left. Out of the popular ones, only Terracotta is supported. It seems that this is a very niche solution and we do not have many options to choose from. In terms of less-known projects, I came across Chronicle-Map, MapDB and OHC. I chose the last one because it was created as part of the Cassandra project, which I had some experience with and was curious about how this component worked:

    So, it's an object database, like Zope's ZODB on Python?

    I like the idea, but I'd like to learn about use cases for it.

    Otherwise, in Java, MapDB is about as far as I'd be willing to go: https://github.com/jankotek/mapdb/

  • what is the best persistent collection library?
    5 projects | /r/java | 2 Sep 2022
    Anyway, without further ado, I found MapDB (https://github.com/jankotek/mapdb) which does exactly that. Of course, they also provide their own Java collection implementations as well, so I suspect using it with Vavr would be a poor idea, but it is very cool in its own right anyway. Of course, there is also Apache Derby and HSQLDB, and those great options with a long history as well. I haven't played with these in a while though, so I might give them a try again soon for some personal stuff.

    In Java I like

    It is more feature rich than you want but in Python I'd probably just use sqlite3 since it is in the standard library.

    We’re using JVector for the vector index and Chronicle Map for the article data. There are several things I don’t love about Chronicle Map, but nothing else touches it for simple disk-based key/value performance.

    I've wrangled data sets in the ~600gb range using nothing but plain old Java and a few beefy boxes. This can all be kept in memory, but you have to go off-heap. You can use Chronicle Map and Chronicle Values to model this data and work with it off-heap in a way that's still very clean and object oriented. 128gb of RAM is cheap these days, whether you're in the cloud or not.
