I am on ES 7.2.0
I create a simple pipeline:
PUT _ingest/pipeline/test_pipeline
{
"description": "test",
"processors": [
{
"split": {
"field": "message",
"target_field": "splitdata",
"separator": ","
}
}
]
}
Then I test it.
GET _ingest/pipeline/test_pipeline/_simulate
{
"docs": [
{
"_source" :{
"message" : "A,,B,,"
}
}
]
}
Results come back like this:
{
"docs" : [
{
"doc" : {
"_index" : "_index",
"_type" : "_doc",
"_id" : "_id",
"_source" : {
"message" : "A,,B,,",
"splitdata" : [
"A",
"",
"B"
]
},
"_ingest" : {
"timestamp" : "2019-10-23T04:25:26.277Z"
}
}
}
]
}
I was expecting two empty fields after the character 'B'.
With an input like this:
GET _ingest/pipeline/test_pipeline/_simulate
{
"docs": [
{
"_source" :{
"message" : "A,,B,,C"
}
}
]
}
I get the expected fields.
{
"docs" : [
{
"doc" : {
"_index" : "_index",
"_type" : "_doc",
"_id" : "_id",
"_source" : {
"message" : "A,,B,,C",
"splitdata" : [
"A",
"",
"B",
"",
"C"
]
},
"_ingest" : {
"timestamp" : "2019-10-23T04:27:38.400Z"
}
}
}
]
}
Edit: Not very hopeful now.
