I have been trying to get a joint genotype for exome bed region from whole genome gvcf. However, this is really slow and I am not sure if this is the right approach to do it. I have more than 600 samples and this has been running for more than 10 days. Can someone please clarify?

module load java
/gatk-4.1.7.0/gatk --java-options "-Xms4G -Xmx32G -DGATK_STACKTRACE_ON_USER_EXCEPTION=true" \
 GenomicsDBImport \
--genomicsdb-workspace-path /scratch/chr19 \
--batch-size 50 \
-L /scratch/chr19.exome.bed \
--sample-name-map /scratch/AllSamplesGvcfChr19.list \
--reader-threads 16

I got the same problem, at the end I moved back to gatk/CombineGVCF ...

Was it faster? Did you do GenotypeGVCFs afterwards?
