Elasticsearch partial update vs full update? -


question: i've got application change document should persisted elasticsearch after it's validated against full document. have retrieve full document! partial update better full update in regards performance there other benefits ?

elasticsearch documentation partial update mentions documents immutable , internally partial updates full update reindex full document.

externally, appears though partially updating document in place. internally, however, update api manages same retrieve-change-reindex process

the documentation mentions following assume "benefit of partial update on full update" don't understand. if there document in shard , full update on or partial update in total 1 request. multiple request mean here ?

the difference process happens within shard, avoiding network overhead of multiple requests

as mentioned above both partial update , full update use retrieve-change-reindex process make updation.

but difference : partial update uses update api achieves retrieve-change-reindex through single client request, while full update uses index api requires separate get , index requests , , that's why full update has network overhead of multiple requests.

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac
