The xsd:float datatype represents IEEE 754 single-precision floating point numbers. As with any floating-point datatype, the precision depends on the size of the number. Numbers close to zero are very precise. Numbers with a large absolute value (large positive or large negative) are less

Zookeeper has an external state - it's configuration file and it's persistent database on disk. If you use --zkConf then your zoo.cfg you'll have something like: dataDir=./ZkData and maybe dataLogDir= or have used --zkData for the snapshot of the in-memory database and the transaction log.

Andy, Richard, Thank you for the feedback. In the graph I have the 2 values as xsd:float so this is how the data is coming In the SPAQL query I tried to cast the float to decimal by using FILTER (xsd:decimal(?value1)!=xsd:decimal(?value1)). I am not sure if this is correct way, but I am now

No, we don't do anything extra to preserve the data. We expected RDF Delta would pick it up automatically. Could you clarify what you mean by preserving? How can we apply it? Thanks, Piotr pon., 17 sie 2020 o 19:06 Andy Seaborne napisał(a): > Did you preserve the Zookeeper database when

Piotr Not used RDF Delta myself but the Zookeeper issues sound familiar When anything is trying to talk to Zookeeper if the ZK node they are trying to talk to stops responding then the ZK client code will fail and then re-establish a session to a diferent node. BUT this isn’t immediate for a

Piotr, It will depend on how long zookeeper takes to resync. One of the factors is how big the zookeeper database has become because when a ZK server starts, it has to process the snapshot and any logs to But while syncing the other zk server should still provide service (read-only) - maybe
