Exactly. Unfortunately I am such person who must find some other NoSQL DB :/ because of these 2 mentioned cases. But I promise to come back later and check if standalone + transactions are ready :) Cheers. -- View this message in context: http://neo4j-community-discussions.438527.n3.nabble.com/Standalone-server-and-transactions-tp3553058p3554646.html Sent from the Neo4j Community Discussions mailing list archive at Nabble.com. ___ Neo4j mailing list User@lists.neo4j.org https://lists.neo4j.org/mailman/listinfo/user
Re: [Neo4j] Standalone server and transactions
Anyway, You are talking now about things that doesn't exist and I have to implement them on my own. I can't imagine RDBMS server that doesn't give me JDBC driver in the box. Unfortunately Neo4j is like this. There is no native transaction-full support so Neo4j can work as standalone server with many connections to it. And that's the point. Now I have to choose one of the: - Neo4j as standalone server with REST without transactions or - Neo4j embedded with only 1 connection with transactions. I can't imagine the situation where DB server is embedded in application (really big application) which allows 1 connection (not 2, not many, but 1!). There is no possibility to have separated machine for DB because then there is no transactions. Transactions in meaning the "core" of persisting data doesn't exist in DBMS...I'm amazed that nobody has thought about these as a "bottleneck problem". -- View this message in context: http://neo4j-community-discussions.438527.n3.nabble.com/Standalone-server-and-transactions-tp3553058p3554188.html Sent from the Neo4j Community Discussions mailing list archive at Nabble.com. ___ Neo4j mailing list User@lists.neo4j.org https://lists.neo4j.org/mailman/listinfo/user

Do You know ANY (mature) RDBMS which is: provides many connection at the same time, transaction-less and is still popular? I don't know any (even SQLite has transactions). And now, somebody (not meaning You) want to convince me that transactions are not needed. At least there strange silent that Neo4j has full transactions (not "batch mode") ONLY in embedded mode and in embedded mode there is allowed only 1 connection. Additional case here is that I read about this after some days of testing the Neo4j in my app. No info in tutorial about this 2 cases what are very important. I didn't even think about it when I have started with Neo4j. I just assume that Neo4j is for sure able to work as standalone server, allows many connections and provides full transactions. Now I know that this is not so obvious if we call something "DBMS". Actually other NoSQL DBMS have the same problem - they don't inform on the first page about transactions and standalone modes at all. You have to read some tutorials or forum threads to get to know...after few days. -- View this message in context: http://neo4j-community-discussions.438527.n3.nabble.com/Standalone-server-and-transactions-tp3553058p3554061.html Sent from the Neo4j Community Discussions mailing list archive at Nabble.com. ___ Neo4j mailing list User@lists.neo4j.org https://lists.neo4j.org/mailman/listinfo/user

But this is the worst one because I have to create custom layer which will work ONLY with my app. This means that I cut the rope that allows me to use Neo4j server simultaneously with other tools (like Neoclipse or some other which appear in the future). -- View this message in context: http://neo4j-community-discussions.438527.n3.nabble.com/Standalone-server-and-transactions-tp3553058p3554027.html Sent from the Neo4j Community Discussions mailing list archive at Nabble.com. ___ Neo4j mailing list User@lists.neo4j.org https://lists.neo4j.org/mailman/listinfo/user
[Neo4j] Standalone server and transactions
Hi I have read as much I was able to read about Neo4j with the topic I wrote below. My imaginations of DB server (doesn't matter RDBMS or NoSQL) is that the crucial things for DB server is interesting from development point of view are (musts!): 1. DB server must be able to work as standalone server 2. DB server must provide transactions. Can anybody guide me through these 2 things in Neo4j world? Ad 1. There are lots of examples to work with Neo4j as embedded. Actually these examples works, I already made some application that was operating quite good (embedded Neo4j was started/stopped by Singleton EJB). The only problem is that I can use DB via application (x)or Neoclipse. Never both at the same time. This is very annoying to stop the app and connect via Neoclipse and vice versa. Ad2. So first thing what I wanted to do was start Neo4j as standalone server. The problem was thtat the only "entry point" to Neo4j server is...HTTP REST. This lib (as I know) is not "managed" by Neo4j project/fellows but some "external" fellow created it. I say - OK, let it be. But the first thing what was written there was "transactions are not supported". Only batch operations but from my point of view this is a bit tricky solution for transactions. Am I missing something? I hope I do, because in this situation, Neo4j isn't actually interesting DB server/solution...but I want it to be. "Standalone server and transactions or GTFO".
