If you are using the ERES in a multi-user environment, multiple users can be exporting reports and charts at the same time, utilizing multiple CPU cores.<\/p>\n\n\n\n

However, if you are using the EC, ER, EDAB or ERES API to export charts locally, the application typically runs in a single thread.<\/p>\n\n\n\n

In the following code block, there’s an example of a single-threaded chart export using the EspressChart API.<\/p>\n\n\n\n

\/\/ do not connect to the EspressManager server\nQbChart.setEspressManagerUsed(false);\n\n\/\/ our chart template is parameterized\n\/\/ it uses a single integer as the argument\nObject queryParams[] = new Object[1];\n\n\/\/ set the argument to "1"\nqueryParams[0] = 1;\n\n\/\/ create an instance of the QbChart object\nQbChart chart = new QbChart((Applet)null, "chartTemplate.pac", queryParams);\n\n\/\/ export the chart to a PNG file\nchart.export(QbChart.PNG, "exportedChart.png");\n<\/pre><\/div>\n\n\n\n
If you run the previous code in a loop (even with different parameter values), it can export as many charts as you want, however, it will export one chart at a time using a single CPU thread. Most of the CPU will be idle.<\/p>\n\n\n\n
\"\"
CPU utilization in a single-threaded application<\/figcaption><\/figure>\n\n\n\n
This will negatively impact the overall performance of your API implementation on a modern CPU with many threads. On the other hand, if you are exporting a single chart or just a few charts at the same time, the export should be finished within a couple of seconds maximum.<\/p>\n\n\n\n
However, it is possible to utilize multiple CPU cores even via the EspressChart API without connecting to the EC, ER, EDAB or ERES server by utilizing Java multi threading. In this example, we are using EspressChart API but similar code can be used for speeding up EspressReport export too. To use this code with EspressReport, replace the QbChart Java class with QbReport. The rest of the code is the same for both EspressChart and Espress Report.<\/p>\n\n\n\n
In this example, we want to export 10,000 charts. All charts will be using the same chart template (although it would be also possible for every chart to be different, with some code changes) but different data.<\/p>\n\n\n\n
The chart template is parameterized. The chart takes one parameter – a customer ID (integer). The chart is loading its data from a MySQL 8 database.<\/p>\n\n\n\n
This is how the chart template looks in Chart Designer.<\/p>\n\n\n\n
\"\"<\/figure>\n\n\n\n
We want to export 10,000 of these charts, each with a different customer ID in as little time as possible.<\/p>\n\n\n\n
We\u2019ll create a multi-threaded Java application using the EspressChart API.<\/p>\n\n\n\n
We\u2019ll create two Java classes:<\/p>\n\n\n\n
BenchmarkRunner.java<\/p>\n\n\n\n
The BenchmarkRunner.java class will be the executable class and it will control the multi-threaded application.<\/p>\n\n\n\n
ChartExporter.java<\/p>\n\n\n\n
The ChartExporter.java class will be doing the actual exporting.<\/p>\n\n\n

This application can use all of our CPU threads to speed-up the exporting.<\/p>\n\n\n\n
Please note that this application makes sense only if you want to export many charts as quickly as possible. Export of a single chart will still be single-threaded.<\/p>\n\n\n\n
