There is only one y1 and one y2 axis. Therefore it
doesn't make sense to have their definition in the
AggregateHandlers, because this would produce multiple
definitions for these axises.
The old method of creating brighter/darker colors was producing color
shades that did not look like the same color. E.g. a darker yellow
looked more like brown.
I am now trying to use hand crafted shades.
The drop down for plot types should only contain plot types that can
be combined. The reason is, that we can only draw images with two
x/y-axis. Therefore a combination of types that would need three or more
axis is not supported.
The writerCache in DataStore did not use the partitionId
in its cache key. Therefore the cache could return the
wrong writer and events were written to the wrong
partition.
Fixed by changing the cache key.
To make it easier/possible to write stable unit test the CSV upload
can optionally wait until all entries have been flushed to disk.
This is necessary for tests that ingest data and then read the data.
We want to be able to use @SpringBootTest tests that fully initialize
the Spring application. This is much easier done with Junit than TestNG.
Gradle does not support (at least not easily) to run Junit and TestNG
tests. Therefore we switch to Junit with all tests.
The original reason for using TestNG was that Junit didn't support
data providers. But that finally changed in Junit5 with
ParameterizedTest.
Recommind is using a pseudo ISO date format for their
log files. It uses a comma instead of a dot for the
second to milli second separator and it does not
add a timezone. Dates without timezone are assumed to be UTC.
