I am very new to ES. We are planning to store hardware test results in the ES instance. We use this results for visualization.
Each test run produces 10 json files, each file with different structure.
Some files will be small and some files might be big.
The size of all these result files is around 5 to 10 MB for each test run.
So my question is,
Since _doc types are being removed in future releases of ES, is it good to have once single index for the test run, with a custom key "type" to differentiate each file. Is it a good option ? or is it better to have separate indexes for each file since the structure is different?
On what basis, we should decide on the number of indexes. Please guide me.
