Change Summary¶
Title | Git Issue | Description |
---|---|---|
New parallelism query parameter for sstream & bulk-consume | 338 | Allows controlling the number of parallel processing threads during streaming. Default is 10. |

Akka upgrade | 402 | Akka libraries minor version upgrade from 2.5.6 to 2.5.9 |
Full-text search improvements | 414 | Infrastructure for improving FTS performance. Solves some cases of timeouts in Elastic Search client layer. |
The SPARQL Trigger Processor Engine now uses consume rather than bulk-consume | 427 | This improves STP's robustness. |

Activated cluster sniffing for Elastic Search clients | 448 | Previously full-text search might fail if the default ES instance didn't respond. Now the client will look for alternative ES instances. |
