Hi all,

I have a table with a version column which is a timestamp as a binary. This is changed every time there is a change/update in the row.

I can transmit this table to elastic but my format is not really correct

`<Sequel::SQL::Blob:0x9b18 bytes=8 content="\u0000\u0000\u0000\u0000\u0001\xE6\u0016\xEF"`  
instead of  
` 00000000000000000001E60016xEF"`

is there a way to correctly import this binary column and set it as a tracking column so when there is a change is this field logstash only updates/sends the changed row to Elasatic ?

i'm breaking my head sinds last night without any luck.

thx in advance
