Primary key with multiple columns?

[Madman600]

I'm trying to add a primary key with multiple columns to store options trade data so only unique 5 minute bars are added. The only way I've found to do it is to define the primary key with a keypath like below. I need to search using a query as shown below, where I want to get bars after a certain time. This all works fine except I'm wondering if this is the best way to do it as the data for the symbol, barTime, strike, expDate, and side seems to be duplicated in the primary key as shown in the image. Is there any way to do what I need to do and avoid the data duplication?

  getDbSchema() {
        var table = {
            name: 'five',
            columns: {
                symbol: {
                    notNull: true,
                    dataType: JsStore.DATA_TYPE.String,
                    enableSearch: true
                },
                strike: {
                    dataType: JsStore.DATA_TYPE.Number,
                    default: 0.0,
                    enableSearch: true
                },
                expDate: {
                    dataType: JsStore.DATA_TYPE.String,
                    enableSearch: true
                },
                side: {
                    dataType: JsStore.DATA_TYPE.String,
                    notNull: true,
                    default: 'U',
                    enableSearch: true
                },
                barTime: {
                    dataType: JsStore.DATA_TYPE.DateTime,
                    notNull: true,
                    enableSearch: true
                },
                price: {
                    dataType: JsStore.DATA_TYPE.Number,
                    notNull: true,
                    enableSearch: false
                },
                open: {
                    dataType: JsStore.DATA_TYPE.Number,
                    notNull: true,
                    enableSearch: false
                },
                close: {
                    dataType: JsStore.DATA_TYPE.Number,
                    notNull: true,
                    enableSearch: false
                },
                high: {
                    dataType: JsStore.DATA_TYPE.Number,

                    enableSearch: false
                },
                vwap: {
                    dataType: JsStore.DATA_TYPE.Number,
                    notNull: true,
                    enableSearch: false
                },
                volume: {

                pk: {
                    primaryKey: true,
                    keyPath: ['symbol', 'strike', 'expDate', 'side', 'barTime'],

                }
            }
        }

   let rows = []
           try {
               const select =
               {
                   symbol: params.symbol,
                   barTime: {
                       '>=': params.sqlStartDate
                   },
                   strike: strike,
                   expDate: params.expDate,
                   side: params.side
               }

               rows = await this.jsstoreCon.select({
                   from: 'five',
                   where: select
               });
           }
           catch (err) {
               console.log(err);

enableSearch = false means no index. Just remove or make it true, then check.
