Hello,
I'm trying to import into a MySQL DB an ENSEMBL file (concretely,
homo_sapiens_variation_66_37 allele.txt.gz ~ 20 GB) using MySQL LOAD
DATA INFILE.
However, it always gets stuck when the index file is around 5 GB. At
that time, the process status is 'Repair with keycache'.
After discovering this file:
ftp://ftp.ensembl.org/pub/ensembl-functgenomics/scripts/DAS/load_bed_source.pl
I've been trying different values of myisam_sort_buffer_size and
myisam_max_sort_file_size parameters with no luck.
MySQL version is 5.1.45.
Has anyone experienced problem like this?
Thanks in advance,
