Loading Elasticsearch indexes
To mount a remote Elasticsearch index into the sgr engine using Splitgraph's
fork of pg_es_fdw,
run:
$ sgr mount elasticsearch -c elasticsearch:9200 -o@- <<EOF
{
"table_spec": {
"table_1": {
"schema": {
"id": "text",
"@timestamp": "timestamp",
"query": "text",
"col_1": "text",
"col_2": "boolean",
},
"options": {
"index": "index-pattern*",
"rowid_column": "id",
"query_column": "query"
}
}
}
}
EOF
The FDW translates local queries into the
Elasticsearch Query DSL.
You can also pass Lucene query strings as query_column equality clauses. For
example, if query_column is set to query, you can use
WHERE query='text_body:chess').
To snapshot the table, making it part of an actual Splitgraph image, use the
sgr import command.
