Hi,
Looking for suggestions on a business case which is being currently
addressed to.
Following is the sample of data we want to store in elasticsearch in
hierarchical format. It is close to a hierarchical synonym tree.
cine,movies,Entertainment
film,movies,Entertainment
One option is to store the data in a single ES document, as follows :
{
"taxonomyName": "Entertainment",
"taxonomyMembers": [],
"taxonomyHierarchy": [
{
"taxonomyName": "movies",
"taxonomyMembers": [
"cine",
"film"
],
"taxonomyHierarchy": []
}
]
}
Another option is to keep each word into separate ES documents, as follows :
{
"taxonomyName": "Entertainment",
"taxonomyHierarchy": [
{
"taxonomyName": "movies",
"taxonomyMember": "cine"
}
]
}
and
{
"taxonomyName": "Entertainment",
"taxonomyHierarchy": [
{
"taxonomyName": "movies",
"taxonomyMember": "film"
}
]
}
We have dictionary of such words, count reaching up-to several thousands,
having hierarchy level up to 5 so far.
We keep on adding/deleting words in bulk from this dictionary, we often
change hierarchy of several words in bulk.
Which of the above seems to be the better structure to store such data? A
single large json document containing all words? Or many small json
documents each with a single word and its hierarchy? Any suggestions?
Thanks,
-- Sujoy.
