# Title: Add indexes to the gene_member table for the biotype_group column
#
# Description:
# The gene_member.biotype_group column was not part of any keys, but was used
# in several queries. The extra indexes will hopefully speed them up a bit.

ALTER TABLE gene_member
  ADD KEY biotype_dnafrag_id_start_end (biotype_group,dnafrag_id,dnafrag_start,dnafrag_end),
  ADD KEY genome_db_id_biotype (genome_db_id, biotype_group);

# Patch identifier
INSERT INTO meta (species_id, meta_key, meta_value)
  VALUES (NULL, 'patch', 'patch_90_91_c.sql|gene_member.biotype_group-index');
