      Description

      alter table big_rocksdb_table ENGINE=ROCKSDB;

      Database crashed due to out of memory:

      what(): std::bad_alloc
      18:18:42 UTC - mysqld got signal 6 ;
      This could be because you hit a bug. It is also possible that this binary
      or one of the libraries it was linked against is corrupt, improperly built,
      or misconfigured. This error can also be caused by malfunctioning hardware.
      Attempting to collect some information that could help diagnose the problem.
      As this is a crash and something is definitely wrong, the information
      collection process might fail.
      Please help us make Percona Server better by reporting any

      key_buffer_size=8388608
      read_buffer_size=131072
      max_used_connections=2
      max_threads=152
      thread_count=1
      connection_count=1
      It is possible that mysqld could use up to
      key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 68315 K bytes of memory
      Hope that's ok; if not, decrease some variables in the equation.
