A GraphQL service to fetch data from a Tango TTS (Tango TimeSeries) HDB (Historical Database) or TDB (Temporary Archiving Database).
- Usage for production (file application.yml from resources):
mvn package
java -jar target/tango-archiving-graphql-extractor-2.0.0.jar- To start in dev a environment (file application-dev.yml from resources):
mvn package
java -Dspring.profiles.active=dev -Dspring.output.ansi.enabled=ALWAYS -jar target/tango-archiving-graphql-extractor-2.0.0.jar- To start with an overridden external configuration
java -jar target/tango-archiving-graphql-extractor-2.0.0.jar -Dspring.config.location=./conf.yml- Some GraphQL queries examples:
Get attributes names for the pattern *status:
{
attributesNames(attributesPattern: "*status")
}Get last values of 2 attributes:
{
attributes(attributeNames: ["tango/tangotest/1/double_scalar","tango/tangotest/1/string_spectrum"]) {
info{
name
format
type
writeType
}
timestamps
read
write
}
}Get values between 2 timestamps:
{
attributes(attributeNames: ["tango/tangotest/1/double_scalar"], startDate: "2017-12-21 16:00:00.000", endDate: "2018-12-31 16:00:00.000") {
read
write
timestamps
info{
name
format
type
writeType
}
}
}- Subscription example:
subscription {
valuesUpdated(attributesNames: ["tango/tangotest/1/double_scalar"]) {
info {
name
format
type
writeType
}
timestamps
read
write
}
