Ma.y NoSQL （Not Only SQL） da.a.a.es were proposed to store a.d query on a.huge a.ount of da.a. Some of them like BigTa.le, PNUTS, a.d HBa.e, ca. be modeled a. distributed ordered ta.les （DOTs）. Ma.y a.ditiona. indexing techniques ha.e been presented to support queries on non-key columns for DOTs. However, there wa. no comprehensive a.a.ysis or compa.ison of these techniques, which brings troubles to users in selecting or proposing a.proper indexing technique for a.certa.n workloa.. This pa.er proposes a.ta.onomy ba.ed on six indexing issues to cla.sify indexing techniques on DOTs a.d provides a.comprehensive review of the sta.e-of-the-a.t techniques. Ba.ed on the ta.onomy, we propose a.performa.ce model na.ed QSModel to estima.e the query time a.d stora.e cost of these techniques a.d run experiments on a.pra.tica. workloa. from Tencent to eva.ua.e this model. The results show tha. the ma.imum error ra.es of the query time a.d stora.e cost a.e 24.2% a.d 9.8% respectively. Furthermore, we propose indexCompa.a.or, a. open source project tha. implements representa.ive indexing techniques. Therefore, users ca. select the best-fit indexing technique ba.ed on both theoretica. a.a.ysis a.d pra.tica. experiments.

This study proposes a.sta.istica. mea.ure a.d a.stocha.tic optimiza.ion model for genera.ing risk-seeking wind power offering stra.egies in electricity ma.kets. inspired by the va.ue a. risk(Va.) to qua.tify risks in the worst-ca.e scena.ios of a.profit distribution, a.sta.istica. mea.ure is proposed to qua.tify potentia. high profits in the best-ca.e scena.ios of a.profit distribution,which is referred to a. va.ue a. best(Va.)in the best-ca.e scena.ios. Then, a.stocha.tic optimiza.ion model ba.ed on Va. is developed for a.risk-seeking wind power producer, which is formula.ed a. a.mixed-integer linea. progra.ming problem. By a.justing the pa.a.eters in the proposed model, the wind power producer ca. flexibly ma.a.e the potentia. high profits in the best-ca.e scena.ios from the proba.ilistic perspective. Fina.ly, the proposed sta.istica. mea.ure a.d riskseeking stocha.tic optimiza.ion model a.e verified through ca.e studies.
