Massive insertion (multiple threads/buckets + non unique index) leads to timeout/excessive retries

3

From Discord Channel (user Kolja): -------------------------- I wrote a small stress test (in Kotlin though) that reproduces the problem a 100% of the time on my machine: https://gist.github.com/koljakube/73062a48afe29ea6fff8d6a55b2a3d2d

After testing, it was found that: 1) Set Darcadedb. typeDefault Buckets to 32, and when 10659 data entries are written, the above logs will begin to appear; 2) Set Darcadedb....

Implement truncate bucket

A truncate command could simply leave page number 1 in a bucket and delete all the other pages. This is similar to a `drop bucket + create bucket`, but in...

Buckets containing vertices could be compressed by relocating vertices in the early pages of the buckets, deleting all the pages at the end that are empty. This would dramatically reduce...

The issue with multi-server events is our RAFT replication protocol: only modified pages are exchanged between servers. So if you update the record #10:100 on server A, its page will...

Since we already have the WebSocket, it could be cool to implement the Java listener API also in the remote database that uses the WebSocket under the hood. This could...

Currently we have `com.arcadedb.serializer.JsonSerializer`, used by the HTTP handlers, and `com.arcadedb.database.JSONSerializer`, used by the documents to serialize into JSON

This is the 1nd part of better reusing the space in pages. - [ ] compress the LinkedList used for edges. New edges are added at the beginning (because the...

SQL query issue with optimization

This following query doesn't work: `select from Chat let users = in('HasChat'), brain = out('CreatedFromAssistant') where #22:1 IN $brain AND ( contextVariables['local:fin'] = '7:106514432' OR @rid = '#7:106514432')` If I...

YouTrack (OrientDB fork supported by JetBrain) created this suite to execute a ldbc-snb benchmark against a Gremlin database: https://github.com/JetBrains/ldbc-snb-interactive-gremlin It would be nice to check ArcadeDB's Gremlin performance and compare...
