Heap Size Configuration for Elasticsearch

Elasticsearch is an underlying search technology used when performing data profiling in Discovery and when performing matching using the matching stages in Spectrum Enterprise Designer. Consider increasing the Elasticsearch heap size in these situations:
  • In Discovery, you run multiple profiles concurrently or you run a profile having multiple tables
  • You have flows that run multiple search index queries in parallel, each of which returns 1,000 or more candidates

To increase the Elasticsearch heap size, open this file in a text editor:


Increase the value in the -Xmx property. The default heap size is -Xmx2048m.
